Kids Count Data Center

There have been substantial changes made to the 2008 American Community Survey (ACS) questions on labor force participation and number of weeks worked.  After thoroughly investigating the extent to which each of the Kids Count indicators of economic well-being may be affected, we believe that the changes in methodology were significant enough to constitute a break in the trend. We therefore do not recommend that you make comparisons to previous years’ estimates.

Because of recent changes to the science assessment, results from 2009 cannot be compared to those from previous assessment years. According to the National Center for Education Statistics:

The content of the NAEP science assessment is guided by the 2009 NAEP science framework. It provides the theoretical basis for the assessment and describes the types of questions that should be included and how they should be designed and scored. As with all NAEP frameworks, the science framework was developed under the guidance of the National Assessment Governing Board with input from hundreds of individuals across the United States, including some of the nation’s leading scientists, science educators, policymakers, and assessment experts.

The 2009 framework replaces the one used for the 1996, 2000, and 2005 science assessments. A variety of factors made it necessary to create a new framework: the publication of National Science Education Standards¹ and Benchmarks for Scientific Literacy², advances in both science and cognitive research, the growth in national and international science assessments, advances in innovative assessment approaches, and the need to incorporate accommodations so that the widest possible range of students can be fairly assessed. 

The assessment resulting from the 2009 framework will start a new NAEP science trend line so results from 2009 cannot be compared with results of previous science assessments. Whenever changes are made to a framework, efforts are made to maintain the trend lines that permit the reporting of changes in student achievement over time. If, however, the nature of the changes made to an assessment are such that the results would not be comparable to earlier assessments, a new trend line is started.

    Every 10 to 15 years the Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics (NCHS) collaborates with State vital statistics offices to revise the official birth certificate. The most current birth certificate revision took place in 2003, and before that, 1989.  Full implementation by all states of the 2003 revised certificate has not yet occurred.  Each year, since 2003 several states per year have adapted the 2003 revised certificate while the remaining states continue to use the 1989 unrevised birth certificate.
    Three birth certificate items featured on the KIDS COUNT Data Center that NCHS has identified as not comparable between the 1989 and 2003 birth certificate revisions are: educational attainment, prenatal care, and tobacco use during pregnancy.
    Below is a chart showing the year that states implemented the 2003 revised birth certificate (as of January 1). For items where the 1989 and the 2003 data are not comparable, results are only reported on the KIDS COUNT Data Center when states have an entire calendar year of the 2003 Revised Birth Certificate or an entire calendar year of the 1989 Unrevised Birth Certificate. States that implement after January 1st are noted as N.A. or not available for that year.

Estimates from both the American Community Survey (ACS) and the Current Population Survey (CPS) are being made available.  Data estimates from the ACS are used in the KIDS COUNT Data Book Child Well-being Index.  They reflect single-year data though are only available back to 2008 when the health insurance question was first added to the survey.  Because of issues of small sample size, the CPS estimates reflect 3-year averages.  Even with a 3-year average, the ACS is considered a more reliable data source for state-level estimates.  We continue to post the 3-year CPS estimates because they are available for a longer time series which may be more useful for certain data analyses.
