    I was wondering what does “S” mean in a dataset? thanks!

  2. Baby2Baby says:


    Do you have have info on children ages 0-12 experiencing homelessness in Los Angeles County and CA, or any stratified data on the number of youth and their ages?

    Thank you for your help!


  3. california rural legal assistance says:

    is there a way I can get suspension and expulsion numbers for kern county and kern high school district broken down by gender and ethnicity?

  4. California Department of Public Health says:

    Hi, I’m viewing Children in Foster Care, by Age. I’m comparing data by “Rate per 1,000” vs. “Number.” Shouldn’t the data behave in same fashion regardless of the data type? For example, the breakdown by age Rate per 1000 is 8.1 and 8.2 for under 1 and Ages 1-2. Number is 4102, 8179 for those same age categories. If the per 1000 figure is almost equal, why does the number measure differ by almost double?

    • says:

      Our data manager contacted you with a response directly, and we wanted to post the answer here in case others are interested. Perhaps the confusion comes from the fact that the “Rate per 1000” values are computed with a denominator of the total number of children within that age group, rather the total number of children in California. The way the rates are calculated is “Number of Children in Foster Care in that age group” divided by “Number of children in that age group” multiplied by 1000. Using your example, the Number value is about double for the age groups “Under 1” and “Ages 1-2” but the Rate per 1000 is similar because the number of children in those age groups turns out to be about double, too.

  5. SanJoaquin Co Office of Ed says:

    Looking for information on how many students are assessed for Special Ed services and found to be not eligible. Thanks!

    • says:

      Our data manager contacted you with a response directly, and we wanted to post the answer here in case others are interested. Unfortunately, we only have data on students who receive special education services. We suggest you contact the Special Education Division at the California Department of Education (

  6. Public Health says:


    Is there a way to query the data by combining schools into one summary table? For example, if I wanted to create a “city” profile based on the results from multiple schools (as opposed to looking at each school parsed out separately), is this possible? Currently, when I look at the “City” level data, I can’t find a summary for all of the schools in that city combined.

    Thank you!

  7. Campus Life Connection says:

    I’m looking for statistics on how many children in Rancho Cordova and in Sacramento County have an incarcerated parent. How can I find that information?

    thank you!
    Jenny Arnez

    • says:

      Thank you for your question! Unfortunately, our site does not have this information. We checked a few other sources (for example, Department of Justice, Current Population Survey), but I did not find this information easily accessible. In the past, we have been interested in having these data ourselves because we do believe that they contribute to the discussion of children’s wellness. Please let us know if you have had success finding these data.

  8. Modesto Jr. College says:

    What is the percentage of young children ages 0-5 who have experienced trauma in the central valley?

    • says:

      In September, we will share a new topic on about childhood adversity and resilience. This topic will cover indicators related to different forms of trauma, and it will be available by county. You will be able to select the counties in the Central Valley. By signing up for E-Alerts, you will know when these data are available as soon as we share them on the site. If you have not already done so, you may want to sign up at at

      On the site currently, we have information about rate of cases of child abuse and neglect, which will capture reported trauma at the hands of caregivers: Below the figures, you may find additional useful information in “Research and Links.”

      Good luck with your research topic!

  9. Shasta College says:

    I teach Human and Child Development at Shasta Community College in Redding, CA.
    I use to help my students compare statistics about children in our community.
    I noticed that many of the topics have no data for our county.
    I’m wondering if this is something my students could help collect?
    For example, the entire section on bullying and harassment has no data.
    I would love for my students to be useful and involved in something that could benefit the community, especially as it relates to research on children and families.
    Let me know if you would be interested.

    • says:

      Thanks for your message and your enthusiasm for data. The challenge that small counties like Shasta pose for us at kidsdata is that for survey data like those we present on bullying/harassment, the sample sizes are also sometimes small. When you see ‘N/R’ on our site, then, this indicates that the sample is too small to be representative, not necessarily that the data haven’t been collected. In order to ensure reliability, our data sources apply a thorough and rigorous methodology, which I suspect is not easy to replicate. That being said, we at the foundation are always interested in partnering around data and would be interested to hear about any creative ways you and your students might have for using data towards community impact.

  10. florida's homeless kids says:

    We are researching the idea to establish a web site for the Florida libraries and other access points that allow homeless children/w/parent (s) to log on and have an active (language they understand) site for K-3rd grade activities/class lessons/ as a means to track how many of our state’s children are out there and need a temporary education and will use the site free, run by volunteers& financed by grants.

    • says:

      Thanks for your message. While we don’t have direct experience creating a site like that, we would encourage any users to reply if they have suggestions.

  11. independent says:

    Hi, I’m looking at urban vs rural demographic area. I see that “children” are defined as individuals under 18 years of age, but how do the data define “urban” and “rural”?

    Thank you

    • says:

      Thank you for your question! I believe you’re talking about this indicator: If so, the definition of “urban” and “rural” are called out in the footnote:

      An ‘urban’ area is defined as a densely settled core of census tracts and/or blocks with at least 2,500 people, at least 1,500 of whom live outside institutional group quarters (e.g., hospitals or nursing homes). Urban areas also include adjacent territory containing non-residential urban land uses as well as territory with low population density that links outlying densely settled territory with the densely settled core. Rural areas include all population, housing, and territory not included within urban areas.

      Hope that answers your question. If not, please let us know!

  12. College of San Mateo says:


    I’m reviewing the data on Disconnected youth in the Data by Topic section. Other sections provide numbers or percentage per 1,000. This section provides only the percentage.

    I’m sure I’m missing something.

    How might I determine the total number of Disconnected Youth in, for example, San Mateo County–the county I’m researching?

    Thanks for your time, and for providing such a great resource!

    • says:

      Thanks for your question, James! You are definitely not missing something; they are intentionally not displayed in this case. On, we display as many data types as each individual data will allow. For this reason, you will see numbers being presented alongside rates or percentages on indicators that were collected administratively (i.e., they are actual counts). However, since these data are survey estimates, displaying percentages, and nothing else, is the most appropriate data-wise. Feel free to email me directly if you would like to discuss further.

  13. Little Green Wheelbarrow says:

    What programs are there to address food deserts (scarce access to fresh fruits and vegetables) in urban areas, either school- or community-based?

  14. Nevada County WIC says:

    On your page delineating child care costs by age (infant or not) and location (county), I do not see the number of hours of child care delivered per annual cost. Should I assume 52.5 hours per week, to cover the workday of a 40 hr/week worker, including over her lunch hour and 30 minutes commute each way?

    Or is this for a range that covers, say, 30 to 55 hours per week?

    If the data only covers 40 hours per week, and not five days per week, I think it should include the extra amount a parent pays to go over 40 hours/week.

    • says:

      Thank you for your question. The California Child Care Resource & Referral Network, the data source for this indicator, uses the Regional Market Rate survey to calculate child care cost, by county. According to the Survey, 35 or more hours per week is considered full-time. Although that does not give you an average number of hours of child care delivered per annual cost, it does indicate that centers offering more than 40 hours would be included in this figure. Feel free to contact the Child Care Resource & Referral Network ( you have any further questions.

  15. Groveland ATOD Project says:

    I need data for a section of one county. The county-wide data contains too many schools with different demographics than the region of interest. I can’t get data for our individual schools because most of them are small, and the data is “LNE” for almost every measure.

    Is it possible to get aggregated data for a group of schools? The aggregated data would be above the LNE threshold, and would give us valuable input for a Drug Free Communities grant proposal we are working on. Thanks!

    • says:

      Hello Steve, does not offer data down to the individual school level, but it is often possible to get this data directly from the data source. If you are looking for data from the California Department of Education, you can query individual school data using DataQuest ( Similarly, you can retrieve school-level California Healthy Kids Survey data from WestEd ( Just follow the ‘Data Source’ link listed below the data in which you are interested and you might be able to get exactly what you are looking for. If you run into any issues, feel free to reach out again; happy to help in any way we can.

    the previous post I meant SECONDARY DATA-SORRY

  17. California State University, LA says:

    I need some help locating secondary date on the following research questions.
    Research questions:
    1) In Alternative Education African American students, is there a relationship between student’s perception of teacher caring and motivation?
    2) In Alternative Education Hispanic Students, is there a relationship between student’s perception of teacher caring and motivation?

  18. says:

    Thanks for your question, Rusty. In the “Regions” section of, you can create a custom profile with multiple data tables of your choice for any location. If that sounds like it might be helpful for your purposes, here are the steps:
    1) Click on Regions in the yellow navigation bar, which takes you here, and then pick any location of your choice. As an example, click on San Mateo County, then School Districts, and then select Burlingame Elementary.
    2) From the Burlingame Elementary page,, click on the “Customize Data” link in the top left part of the page, right under the black Burlingame Elementary header.
    3) From the Customize Data page,, select any indicators of your choice (as many as you’d like across the different topics) and hit the submit button. That will take you to a custom profile with multiple tables for that school district, such as this one:

    In the “Topics” section of (for example, pages such as this:,4,8,5,6,7,9,13,14,15,16,18,19,20,17,21,22,23,24,25,26,27,28,1794,30,31,32&ch=1079), you can only customize one chart at a time, though one advantage here is that you can view multiple locations in each chart (e.g. if you wanted to see data for both Burlingame Elementary and San Mateo County).

    Please let us know if you have further questions.

    A question from our blog: Do you have statistics on the percentage of hospitalized children for mental health issues have been or are now associated with Child Protective Services?

  20. NRDC says:

    What is the percentage of San Joaquin County children, by coiunty, that bring an asthma inhaler to school?

    • says:

      Thank you for your question. We are not aware of a public data source with this information, but the organizations listed in the Research and Links section of the Asthma topic ( may have some ideas or useful information for you. If you find a source, please let us know. Does anyone have any other suggestions?

  21. Edgewood Center for Children and Families says:


    I am interested in findng out the poverty rates among the group: Children in the Care of Grandparents (Regions of 250,000 Residents or More): 2009. Specifically for San Joaquin County.

    • says:

      Thank you very much for your question!

      We do not currently present the poverty status of children in the care of grandparents for counties on However, here is some information that may be useful from our data source: The U.S. Census Bureau’s American Community Survey (

      According to 2009 1-year estimates for San Joaquin County:
      • Median income of families led by grandparents: $65,141
      • Number of grandparents living with their own grandchildren whose family income in the past 12 months was below the poverty level: 2,685
      • Number of grandparents living with their own grandchildren whose family income in the past 12 months was at or above the poverty level: 19,878

      These are just a few of the data choices available. We encourage you to look on the ACS site for additional data.

      Again, thank you for the question.

  22. Health Services Agency/Stanislaus says:

    A physician in our county is interested in getting statistics about injuries to children in foster care, group homes, daycare and/or babysitting. I cannot find any information specific to injuries to that demographic group on or EpiCenter. Does anyone know of one or more sources of data specific to this demographic group that include both unintentional and intentional injuries (including death)? Our Social Services department has data on abuse (intentional injuries) but not “accidents.”

  23. Playworks says:

    I am looking for school-level data that has disciplinary referral data. I know about Dataquest but am looking for any other data sets that might be available.

    • says:

      Thanks for the question. We’re not aware of another source besides DataQuest that offers uniformly collected disciplinary data at the school level in California, but here are a couple of other websites that might be of interest:

      You also could contact the California Department of Education to see if they have other suggestions. Or you could inquire directly with the schools or school districts of interest to you.

      Does anyone else know of a source for this?

  24. says:

    Thanks very much for the question. does not have data correlating high school dropout and incarceration rates, but here are some resources and publications that might be useful:

    • High School Dropout Rates. Summary by Child Trends DataBank. (Updated 2011).

    • Dropout Rates in the United States: 2007. (2009). U.S. Department of Education.

    • High School Dropouts and the Economic Losses from Juvenile Crime in California. (2009). Belfield, C. (Queens College, City University of New York) and Levin, H. (Teachers College, Columbia University).

    If anyone knows of additional sources of information on this topic, please post a comment here.

  25. Sacramento Children's Home says:

    I’m wondering if there is a way to see statistics for reading levels and foster youth together. Is there a way to see if a correlation exists between below grade level reading comprehension and foster youth?

  26. The Parent Movement says:

    Hello, thank you for the current survey information regarding what parents are saying about their children and school. I am currently working with Vallejo Unified District and their African American parents. Do you have any data supporting African-American children, especially boys in drop-out rate, graduation, suspension, parent involvement, behavior, testing levels etc in comparison to other ethnic groups? Thank you for all the work you do in this needed area of children development.

  27. Ventura County Office of Education says:

    Do you have any information about availability, accessibility and cost of child care for ages 0-3? In addition, I’d be interested in information you might have on this age group re: health, poverty, and types of households they’re in (single parent vs married, etc). I’m looking for information for Ventura County.

  28. Sutter County Public Health says:

    It would be helpful to have local data on birth defects. Our numbers are low, so it might have to be regional data, but I haven’t been able to locate stats on rates of birth defects locally and in California (those that might not be fatal, but cause disability). If you’re aware of sources for this data, please let me know.

  29. San Mateo County Health System says:

    A community partner of ours is interested in teen pregnancy by city within San Mateo County. Where can I access this information? Thank you.

    • kidsdata says:

      My understanding is that data on teen pregnancy is not available even at the state level, never mind the county or city level. You can, however, get teen birth rate data by zip code from the Healthy City website (

  30. Westside Childrens Center says:

    Our service area for funding and reporting is defined by postal zip codes and the data you provide is by city. Can you provide data at the zip code level?

    • says:

      At this time, we don’t offer zip code level data — or, for that matter, data by Census tract or individual school. The reason for this is two-fold:

      In many cases, the data sources available on simply don’t collect data at a more granular level than city, school district, or county (there are even some sources that only offer data at the state level). And if more localized data are available, numbers may be so small, that the data may not be reliable. In fact, in some less populated regions, there are too few children in the entire county to produce reliable data.

      Also, started out by offering data for just two counties (San Mateo and Santa Clara), and then the Bay Area. In expanding kidsdata statewide, we had to make a choice about where to place our resources — we chose to broaden the site’s geographic reach from 6 counties to all of California, instead of providing even more local data for the Bay Area. It was a tough call – and we still think about the feasibility of offering finer-level data.

      There are, however, some places you may be able to find the data you’re looking for. You can try HealthyCity, or the Census Bureau’s zip code data page. Does anyone know of other sources?

  31. CAPMC Head Start says:

    Where can I find data on Physical Health: health insurance coverage 2008 & 2009 for Madera County and Mariposa County

    • kidsdata says:

      On kidsdata, our health insurance coverage indicator comes from the California Health Interview Survey (CHIS), which releases data every other year. We do expect the 2009 data by the end of the year, but 2008 won’t be included. In the meantime, I recommend using the newly-available data on health insurance coverage from the American Community Survey. From this website: select 2009 data, click subject tables, then on the next screen choose County as the geographic type and select your county (Madera is available, Mariposa is not). The health insurance coverage fact sheet gives an estimate of the number and percentage of children under 18 without health insurance.

  32. Fine Development says:

    Can you tell me what the percentage or how many kids 5-18 attend private school in Contra Costa or Alameda County?

    • kidsdata says:

      Thanks for your question. I don’t know of a source for county-level data on enrollment in private or parochial schools, and I don’t think one exists. You could generate an estimate by comparing the child population for a given year with public school enrollment.

      Perhaps a national association like this one would be helpful – They cite data from the National Center for Education Statistics and would know if local data are available.

  33. CSBA says:

    How many children in California public schools come from single-parent homes? Is it possible to find out how many districts/county offices offer support for parents in the form of parenting classes, training, school orientation etc? How many pregnant, parenting teens are enrolled in California public schools?

    • says:

      The California Department of Education does not, to my knowledge, collect or publish data on the family structure of public school students. On kidsdata, you can find family structure data for large counties and cities here: and for counties, cities, and school districts with 20,000+ residents here: You should note that these data come from the Census Bureau’s American Community Survey and aren’t based on public school enrollment. However, they can give you an approximation of the number and percentage of children in a community with single and married parents.

      As for your question about parent support programs, I don’t know of a source for that kind of data. However, since all Title I schools are required to have some sort of parent involvement program, perhaps someone who works on Title I at the CA Dept. of Education can help you find the data you want.

      The California Department of Education offers these reports on pregnant and parenting students:

  34. kids at work says:

    How many low income kids attend preschool?

    • kidsdata says:

      Good question. I don’t know of one unified source for that data.

      You can get information on enrollment in Head Start from the California Head Start Association (

      The California Child Care Resource and Referral Network is another potential source of data: From their site, you can find the resource and referral organization for your county, which may have some of the data you’re seeking.

      The First 5 commissions in some counties have done assessments of school readiness, which often include data about preschool enrollment by income level. You can find your local First 5 here:

      Do others have suggestions?

  35. Ventura County Office of Education says:

    Hi. I’m looking for recent data on Ventura County households receiving public assistance, and data on families with children living in poverty – both by city. Is this data available?

  36. Voices of the Middle East & North Africa at KPFA Pacifica Radio says:

    Hi there! I’m seeking health info about Middle Eastern, or Arab, kids in Calif. Is that data available on the site? Thanks 🙂

  37. Open Medicine says:

    Can we download specific data sets to use locally (e.g. in XLS, CSV, or tab-delimited formats)? Specifically we’re interested in a number of diseases on a school by school basis? e.g. autism, cancer. It would also be useful to have ancillary data around those institutions (e.g. exact address). Is such data available?

    Wonderful resource, thank you.

  38. Shipyard Trust for The arts says:

    Can you point me to some publications, statistics, etc., that show that educational success is improved in children who are provided with arts programming (whether in school or during after-school programs). I have often heard this quoted, but don’t know where the data comes from.

    Thank you.

      You might check out the website of Project Zero at the Harvard Graduate School of Education: They conduct research about learning and the arts.

      Americans for the Arts ( has an arts policy database with links to research abstracts like “Involvement in the Arts and Academic Success in Secondary School.”

      A search on Google Scholar ( might be helpful to you as well.

      For research that’s not available online, don’t forget to use your local public library.

    How does the CA income compare to other states?

    • says:

      Thanks for your question. The KIDS COUNT Data Center is a great resource for comparing California to other states on measures of child well being. Here’s their homepage:
      Be sure to click “Data Across States” if you want to compare California to other states.

      According to KIDS COUNT, California ranks 31st out of 50 states in the median income of families with children (i.e. 30 states have a lower median income for families with children). Since California is a high-cost state, comparing the median income across states might not tell you everything you want to know. You might also want to compare California to other states on such measures as the percentage of children living in low-income working families or the percentage of children in poverty. KIDS COUNT has many relevant indicators

    A question from our Facebook page:

    What is the mobility rate (aka,how many times they move) of children in LA County?

    Closest we have on is for foster kids, noting their number of placements:

    Anyone know of a data source for this?

  41. Pierrette Mimi Poinsett MD says:

    I am having some difficulty accessing Child/Adolescent mental health care states for North Bay CA – Sonoma Cty in particular. Interested in percentage of kids/teens serviced, major diagnoses at the very least.

    • admin says:

      We often hear about the need for more publicly accessible data on mental health issues, especially at a local level. We’re not aware of a centralized source of uniformly collected data on mental health care services and/or diagnoses, unfortunately. At this point, the best starting point for Sonoma data on children/teens receiving services and their major diagnoses most likely would be the Sonoma County DHS Mental Health Division.

      Here is some related information that may be useful:

      • The California Healthy Kids Survey includes some questions related to student mental health, and data generally are available at the county and school district level across the state. For example, you can get the percentage of 7th, 9th, and 11th graders who report symptoms of depression and the percentage of students reporting protective factors such as having caring relationships with adults at school, among other data. These data also will be added to soon.
      • You might have seen the percentage of hospital discharges among ages 0-17 due to Mental Diseases and Disorders in Sonoma County on We will soon add data on the rate of self-inflicted injury hospitalizations for ages 5-20 for your county, too.
      • At the California Department of Education’s DataQuest site, you can find the percentage of special education students in Sonoma County and its school districts by type of disability, including Emotional Disturbance.
      • While not local, some statewide information on emotional health is available from the National Survey of Children’s Health. There you can find California data on the prevalence of problematic social behaviors, the presence of positive social skills, the percentage of children taking medication for emotional issues, and much more.

      Thank you for the question, and please keep us posted if you find additional sources of local data on mental health issues. We welcome other users to offer any suggestions, as well.

    What happened to the indicators about fruit and vegetable consumption?

    • admin says:

      The California Healthy Kids Survey discontinued the questions about eating fruit and vegetables, so we removed them from kidsdata.

  43. says:

    Why do I see “LNE” for my region?

    • admin says:

      LNE (Low Number Event) means that the number of, say, deaths in a given region and time period was too low to calculate a reliable rate. In this example, if there were fewer than 20 deaths in a given age group and county in 2005-2007, you will see LNE. In some cases, you will be able to find the numbers even when rates are suppressed. Check the “Customize this Table/Chart/Graph/Map” to see if you have the option of switching between rates or percentages and numbers. If you are looking for the number of deaths, be sure to click on the “See Related Data” link on the left side of the page. This list of related data includes the number of deaths in each age group, by leading cause of death.

  44. says:

    Where does the data on come from?

    • admin says:

      To find the data source for any indicator, click on the “Add Regions/View Notes” link on summary pages like this one, or from any data page scroll down to the bottom of the chart, table, map, or graph. Nearly all data on the site are from public sources, though some indicators come from a Lucile Packard Foundation survey of parents about their child’s well being. For more information, view a list of the data sources.
