Measures of Inequality

Percentage of Household Income Distribution, by Quintile: 2017

Income is not distributed evenly across California households. Across the state, some families can comfortably provide for their children’s needs and wants while other families struggle to provide basic clothing, food, and shelter. Some level of income inequality is expected, but when a portion of families cannot support their children’s basic needs, then it is a sign that income inequality has become too wide and poverty has become too deep.

Kidsdata has added new measures of income inequality: Household Income Distribution, by Quintile and the Gini Index of Household Income Inequality, with data available by city, county, school district, and legislative district. The indicator, Household Income Distribution, ranks households by their level of income, divides them into five equally sized groups, then determines the share of aggregate income that each quintile receives, where 20% for each group would represent income equality. The Gini Index expresses income inequality on a scale of 0 and 1, where 0 represents income equality.

How much of the pie do the highest earners get in California? Those in the highest quintile earned an estimated 52% of all household income in 2017, compared with a 3% share of total income earned by households in the lowest quintile.

Two counties (Marin and San Francisco Counties) with the highest level of income inequality in California, as measured by the Gini index, also have some of the highest family median annual incomes in the state, among counties with data in 2017.

While some income inequality is inherent in the economic structure of our society, extreme disparity reflects social and political choices. Let us prioritize children by shaping policies and practices that ensure their basic needs are met so that they may reach their maximum health potential.

Measures of Poverty

Children in Poverty, Federal Poverty Threshold, Ages 0-17: 2008-2017

 

Too many families lack the means to meet their children’s basic needs. Poverty directly impacts access to housing, food, child care, education, and health services, and indirectly affects the ability of parents to meet their children’s social and emotional needs – all crucial to children’s health, development, well-being and future success.

Kidsdata has released updated data on three ways to measure poverty: the federal poverty threshold, the Supplemental Poverty Measure (SPM), and the California Poverty Measure (CPM). These three measures have different historical origins and incorporate different components of poverty. As with all of the topics we address, details about how an indicator is measured are provided in the “Measures of” section under tables and figures.

Kidsdata and the Population Reference Bureau recently reviewed data about poverty starting at birth. Learn more.

How are California children faring? Based on the federal poverty threshold, 18% of California children who were ages 0 to 17 were below the family poverty threshold of $24,858 in 2017, similar to the rate a decade ago. This measure compares pre-tax cash income against a threshold of three times the cost of a minimally adequate diet in 1963, adjusted for inflation. It is best used for measuring poverty over time, and it forms the basis for some administrative determinations.

Based on the SPM, 22% of California children who were ages 0-17 were in poverty in 2016. This measure builds on the official poverty measure by accounting for expenditures and resources such as utilities and state-level differences in housing costs and government benefits and tax credits. It is useful for national and state comparisons.

Children in Poverty, California Poverty Measure (CPM), by Age Group: 2014-2016

Graphic of California Poverty Measure 2019

Based on the CPM, 23% of California children who were ages 0-5 were in poverty in 2014-2016. The CPM refines poverty measurement by accounting for expenditures and resources that are California-specific such as regional differences in housing cost. It is best used for in-state assessments and comparisons.

 

Policy and programmatic planning can influence poverty, even in areas where it may not seem relevant. For example, transportation planners might consider how public transit routes can efficiently connect their higher poverty and more rural constituents to health facilities. Addressing child poverty is essential to assuring a vibrant social and economic environment.

Poverty from Birth

Poverty can alter children’s developmental trajectories in cognitive, socio-emotional, and physical health. The effects of poverty on child health and well-being can begin during pregnancy, as low-income women are more likely to experience risk factors such as malnutrition and stress, and are less likely to receive prenatal care. Children who face economic hardship when they are young, or who experience deep and prolonged poverty, are at greatest risk for poor outcomes.

A 2-page overview of this topic is available here.

Kidsdata and the Population Reference Bureau also reviewed data about poverty starting at birth. The analyses included poverty among infants ages 0-2 since 2012, among children ages 0-5 since 1969, and among children ages 0-17 since 1959. See links to the data sets below.

Childhood Cancer Rates Higher for Older Youth

Childhood Cancer Diagnoses, by Age Group: 2011-2015

Childhood cancer rates of diagnosis are higher among older youth. Similar to rates in the United States, 23 per 100,000 teens ages 15-19 were diagnosed with cancer in California from 2011 to 2015 compared with 16 per 100,000 children under age 15. Difference in cancer rates by age is consistent across race/ethnicity groups. Moreover, older and younger youth are diagnosed with different types of cancer.

Pediatric cancer care is highly specialized depending on the type of cancer. The patient’s age also plays a role in determining the best medical approach to provide each child with the highest chance of survival and full recovery. Palliative care, which provides supportive services for sustaining quality of life during and after treatments, also should be age-specific. Many of us can play a role in improving the quality of life for pediatric patients and their families as they face complex physical, emotional, and logistical challenges throughout diagnoses, hospital stays, and beyond.

Policies and programs are key to maximizing positive health outcome and quality of life for pediatric cancer patients.

New to Kidsdata: Population Projections on California’s Children

Projected Child Population Counts, by Race/Ethnicity: 2020 to 2060

New indicators on projected population point to stagnation of the child population from 2020 to 2060 across all racial/ethnic groups. With an unchanging child population and growing adult population, the importance of children becomes ever greater. Guest author, Beth Jarosz from the Population Reference Bureau, explores these new indicators and explains how they can help inform policies and programs that support children’s health and well being.

California’s total population is expected to grow by more than 10 million people (25 percent) to nearly 51 million between 2020 and 2060. However, the child population is expected to remain virtually unchanged, at just over 9 million, over this same period of time. This forecast, from the California Department of Finance, is based on the current population as well as projections about birth rates, death rates, and migration patterns. Low birth rates contribute to the stable child population forecast while long life expectancy and net in-migration result in projected population growth at older ages.

Population forecast information is valuable for many reasons. Forecasts provide decision makers and the public with valuable clues about the future size and characteristics of the population. At the most basic level, a forecast suggests whether a population is going to grow, shrink, or remain about the same. Many forecasts, including those presented here on Kidsdata.org, also provide predictions about the age and gender, racial/ethnic composition, and geographic location of the population in the future.

Forecast data are used to predict and plan for future needs such as schools and health care facilities. If a community is expected to grow, local officials would plan for additional school and health care facilities to meet the needs of the growing population. If a community is expected to shrink, officials would want to start planning for how to use any no-longer-needed space. Forecast data are also helpful in what-if analysis. For example, an analyst might ask, “If we could eliminate racial/ethnic disparities in child poverty, what would the effect be on the overall child poverty rate?” Forecast data help to answer those questions.

The New Importance of Children in America

A report from the Lucile Packard Foundation for Children’s Health explores the economic impact of declining birth rates. Ensuring the health and well-being of children in the U.S. has never been more critical to the nation’s economic and political future. The shortage of children means each child—regardless of gender, ethnicity, geographic residence or economic background—is proportionately more important to our future than ever before.

Troubling Data on Lesbian, Gay and Bisexual Youth in California

The Kidsdata Issue Brief: Lesbian, Gay and Bisexual Youth in California highlights findings from our latest data release on youth in schools.

Disparities among youth based on sexual orientation are startling. Across many indicators of health and well being, lesbian, gay and bisexual (LGB) youth in California reported negative behaviors and consequences at about twice the rate of straight youth. Alcohol and drug use were higher, feelings of depression were more common, and skipping school was more frequent among LGB youth.

Addressing these issues early through policies and programs that promote a positive school climate can help mitigate these behaviors and their effects. By maximizing public funding streams, providing enhanced health care services, and integrating systems of support, all students, including LGB students, can experience better long-term health and well being.
