Underlying cause of death is classified in accordance with the International Classification of Disease. Deaths for 1990-98 are classified using the Ninth Revision (ICD-9). Deaths for 1999 and beyond are classified using the Tenth Revision (ICD-10). The mortality data on the Compressed Mortality File are based on records for all deaths occurring in the fifty states and the District of Columbia. Deaths to foreign residents and residents who died abroad are excluded. Population estimates for 1991-99 are bridged-race intercensal estimates of the July 1 resident population. These estimates were created by the U.S. Census Bureau, Population Division in collaboration with the National Center for Health Statistics and the National Cancer Institute.

Definitions: Births to teenagers by age group. Rate is per 1,000 females in each age group. Data reflect the mother’s place of residence, rather than the place of the birth.

This measure of teenage childbearing focuses on the fertility of all females ages 15 to 19, regardless of marital status.
Rates are not available for cities. Because population estimates for cities by gender and age are not available, it is not possible to calculate rates and therefore data for cities are limited to just the number of teen births.
Rates for states and the U.S. from 1991 through 1999 are based on revised population estimates that are consistent with results from the 2000 Decennial Census. The Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS) revised their rates from 1991 through 1999 to provide more accurate estimates of fertility and mortality levels during the 1990s. The U.S. Census Bureau's data set for state-level intercensal estimates only had data for 5-year age groups after age 1. (In other words, the data set had 1991 to 1999 state estimates for females ages 15 to 19, but not for females ages 15 to 17). As a result, staff at the Population Reference Bureau generated state-level estimates of 15- to 17-year old females by first calculating the ratio of females ages 15 to 17 nationwide to females ages 15 to 19, then applying the ratio to each state's female population ages 15 to 19, making sure the sum of the newly-derived state figures matched the independent national total for females ages 15 to 17. Rates for the Virgin Islands (2000) have been updated using population estimates based on the 2000 Census.

Definitions: Teenagers between the ages of 16 and 19 who are not enrolled in high school and are not high school graduates. Those who have a GED or equivalent are included as high school graduates in this measure. The measure used here is defined as a “status dropout” rate. Inclusion of the group quarters population in the ACS in 2007 could have a noticeable impact on the universe population for this age group. Therefore, the 2007 ACS estimates might not be fully comparable to estimates prior to 2006.

Data Source: Population Reference Bureau, analysis of data from the U.S. Census Bureau, Census 2000 Supplementary Survey, 2001 Supplementary Survey, 2002 through 2008 American Community Survey.

The data for this measure come from the 2000 and 2001 Supplementary Survey and the 2002 through 2008 American Community Survey (ACS). The 2000 through 2004 ACS surveyed approximately 700,000 households monthly during each calendar year. In general but particularly for these years, use caution when interpreting estimates for less populous states or indicators representing small subpopulations, where the sample size is relatively small. Beginning in January 2005, the U.S. Census Bureau expanded the ACS sample to 3 million households (full implementation), and in January 2006 the ACS included group quarters. The ACS, fully implemented, is designed to provide annually updated social, economic, and housing data for states and communities. (Such local-area data have traditionally been collected once every ten years in the long form of the decennial census.)
This measure focuses on teens ages 16 to 19 rather than young adults 16 to 24 because a large share of 18- to 24-year-olds migrate across state lines each year. The high interstate migration rates confound the connection between state policies and programs and state dropout rates. Raw numbers are rounded to the nearest thousand. Teens who are high school dropouts.

Definitions: Teenagers between age 16 and 19 who are not enrolled in school (full- or part-time) and not employed (full- or part-time). This measure is sometimes referred to as “Idle Teens” or “Disconnected Youth.” Inclusion of the group quarters population in the ACS in 2007 could have a noticeable impact on the universe population for this age group. Therefore, the 2007 ACS estimates might not be fully comparable to estimates prior to 2006.

Because of the addition of group quarters in 2006, estimates between 2005 and later years are not fully comparable for this item. Teens not attending school and not working.

Definitions: The share of all children under age 18 living in families where no parent has regular, full-time employment. For children living in single-parent families, this means the resident parent did not work at least 35 hours per week, at least 50 weeks in the 12 months prior to the survey. For children living in married-couple families, this means neither parent worked at least 35 hours per week, at least 50 weeks in the 12 months prior to the survey. Children living with neither parent were listed as not having secure parental employment because those children are likely to be economically vulnerable. Children under age 18 who are householders, spouses of householders, or unmarried partners of householders were excluded from this analysis. This measure is very similar to the measure called "Secure Parental Employment," used by the Federal Interagency Forum on Child and Family Statistics in its publication America's Children: Key National Indicators of Well-Being.

Definitions: The share of children under age 18 who live in families with incomes below the federal poverty level, as defined by the U.S. Office of Management and Budget. In calendar year 2008, a family of two adults and two children fell in the “poverty” category if their annual income fell below $21,834.

The federal poverty definition consists of a series of thresholds based on family size and composition. In 2000, the poverty threshold for a family of two adults and two children was $17,463. Poverty status is not determined for people in military barracks, institutional quarters, or for unrelated individuals under age 15 (such as foster children).  The data are based on income received in the 12 months prior to the survey. Children in poverty.

Definitions: Children under age 18 who live with their own single parent either in a family or subfamily. In this definition, single-parent families may include cohabiting couples and do not include children living with married stepparents.
