Children Overweight or Obese by BMI

Data layer displays information about student performance on Body Composition component of the FitnessGram® physical fitness test. Body Composition is assessed using student Body Mass Index (BMI). Data is available for select states (CA, GA, NY, TX, WV), and displays the percentage and total number of students who are overweight or obese (not in the Healthy Fitness Zone).

Rural vs. Urban Household Poverty

This layer displays information about the difference between rural and urban childhood poverty across the United States. Data are based on census-tract level information from the 2008-12 American Community Survey. Census tracts are defined as urban or rural based on 2010 US Census Bureau definitions; tract level information is then aggregated to and displayed at the Public Use Microdata Area (PUMA) geographic level.

Children with Over 4 Hours of Screen Time per Day

This layer displays the percentage of children age 0 – 17 whose parents report that they spend more than 4 hours per day, on average, watching television or playing video games. This state-level data comes from the 2011-2012 National Survey of Children’s Health (NSCH). For additional map layers from this series, search the Map Room for the term NSCH .

Rural vs. Urban Childhood Poverty

This layer displays information about the difference between rural and urban childhood poverty across the United States. Data are based on census-tract level information from the 2010-14 American Community Survey. Census tracts are defined as urban or rural based on 2010 US Census Bureau definitions; tract level information is then aggregated to and displayed at the Public Use Microdata Area (PUMA) geographic level.

Teen Birth Rates by County, 2010 and 2015

This dataset contains estimated teen birth rates for age group 15–19 (expressed per 1,000 females aged 15–19) by county and year. Hierarchical Bayesian space-time models were used to generate hierarchical Bayes estimates of county teen birth rates for each year. Data are provided by the Centers for Disease Control and Prevention (CDC) National Center for Health Statistics (NCHS).

DEFINITIONS

Estimated teen birth rate: Model-based estimates of teen birth rates for age group 15–19 (expressed per 1,000 females aged 15–19) for a specific county and year. These annual county-level teen birth estimates “borrow strength” across counties and years to generate accurate estimates where data are sparse due to small population size. The inferential method uses information—including the estimated teen birth rates from neighboring counties across years and the associated explanatory variables—to provide a stable estimate of the county teen birth rate.

NOTES:

Data on the number of live births for women aged 15–19 years were extracted from the National Center for Health Statistics’ (NCHS) National Vital Statistics System birth data files for years 2003–2020.

Population estimates were extracted from the files containing intercensal and postcensal bridged-race population estimates provided by NCHS. For each year, the July population estimates were used, with the exception of the year of the decennial census, 2010, for which the April estimates were used.
