Age

The Age datasets are reported once per year by the United States Census. The dataset is available to download through the Urban SDK Data Hub for the years 2015 - 2020. The data has been aggregated to the census tract. The US has seen a trend in older populations, with a median age over 40 years old in many states. In addition, there is an increase in the number of men at older ages. The composition of a population's age can provide insight into future socio-economic trends.

Census Age Definition

The Census Bureau collects information about age in two questions- what is your age, and what is your birthdate. This helps to ensure the accuracy of age data. Highlighted by the Census, Age is a critical element in determining federal funding, as well as a basic demographic characteristic that is crossed by social characteristics, such as marital status and education, and economic characteristics, such as labor force participation and poverty.

Age Categories

The U.S. Census Bureau aggregates age data into four-year brackets:

  • Total Population

  • Under 5 years

  • 5 - 9 years

  • 10 - 14 years

  • 15- 19 years

  • 20 - 24 years

  • 25 - 29 years

  • 30 - 34 years

  • 35 - 39 years

  • 40 - 44 years

  • 45 - 49 years

  • 50 - 54 years

  • 55 - 59 years

  • 60 - 64 years

  • 65 - 69 years

  • 70 - 74 years

  • 75 - 79 years

  • 80 - 84 years

Detailed Calculations

geo_id

The “GEO.ID” field contains 14-digit codes that identify the summary level of data, the geographic component of the data, and FIPS codes that uniquely identify the data. For example, the 14-digit “GEO.ID” for Harris County, TX is “0500000US48201” where “050” represents the summary level of the data, “0000” represents the 2-digit geographic variant, and the 2-digit geographic component, “US” represents the United States, “48” represents the state of Texas and “201” represents Harris County.
