Population Change, 2018 by County, Population Estimates and Components of Change 2016-2018

The Census Bureau’s Population Estimates Program (PEP) produces estimates of the population for the United States, its states, counties, cities, and towns, as well as for the Commonwealth of Puerto Rico and its municipios. Demographic components of population change (births, deaths, and migration) are produced at the national, state, and county levels of geography. Additionally, housing unit estimates are produced for the nation, states, and counties.

PEP annually utilizes current data on births, deaths, and migration to calculate population change since the most recent decennial census and produce a time series of estimates of population, demographic components of change, and housing units. The annual time series of estimates begins with the most recent decennial census data and extends to the vintage year.

4th Grade Reading Proficiency by school district and county, 2015-16

This layer displays reading proficiency rates for counties and school districts across the United States. Data are acquired from the US Department of Education (ED) EdFacts 2015-16 data tables.

Change in Area Deprivation Index Scores (2013 to 2015) by Census Block Group

This map layer displays the change (+/-) in Area Deprivation Index (ADI) scores between the 2013 and 2015 datasets. The ADI is a rankings of neighborhoods by socioeconomic status disadvantage in a region of interest (e.g. at the state or national level). It includes factors for the theoretical domains of income, education, employment, and housing quality. It can be used to inform health delivery and policy, especially for the most disadvantaged neighborhood groups. The 2015 ADI (v2.0) was constructed using the 2011-2015 5-year estimates from the US Census’ American Community Survey. The methods are identical to the 2013 ADI construction.

Chronic Absenteeism by School District, 2015-16

This layer presents data on chronic absenteeism from the U.S. Department of Education’s CRDC. A chronically absent student is one who misses 15 or more school days in a school year. A student is considered absent if they are not physically present on school grounds or participating in approved off-site instruction or related activities for at least half the school day.

  • Absences are counted when a student misses 50% or more of a school day.
  • Days with less than 50% absence are not counted.
  • The total number of absences reflects all school days missed, regardless of the reason (e.g., illness, suspension, or family responsibilities) and whether the absence is excused or unexcused.

School district data are compiled from school-level records. Calculated percentages represent chronic absenteeism only for schools within the district that have valid, unsuppressed data. For more details, refer to the CRDC’s definition of Chronic Student Absenteeism.
