The just released demographic updates now available on the HomeTownLocator State Gazetteers are point estimates for July 1, 2017. As usual, the update also includes forecast growth rates for the next five years for every incorporated city, town, village, Census Designated Place (CDP), county and county equivalent, ZIP Code Tabulation Area, and neighborhhood (Census Block Group) in each of the 50 states.
The four new population parameters added with the 2017 update include:
- Daytime Population: Workers
- Daytime Population: Residents
- Total Daytime Population (TDP)
- Ratio of TDP/Total Population
If the ratio of the TDP to Total Population is greater than 1, the location gains population during the day when commuting workers are present. If the ratio is less than 1, the location is more of a bedroom community where people commute to another place for work.
The HomeTownLocator gazetteers have very easy to use tools to help you explore local information. As an example, the Florida Research Tools page helps you find information or do comparisons of locations within a single state.
The State Demographic Data Comparison Tool allows you to easily compare states to one another.
If you’re interested in comparing cities, towns, counties, and ZIP Codes nation wide, then you’ll find the Compare Selected City, Town, County & ZIP Code Data Tool very easy to use.
The data used in the annual updates are produced by Esri Demographics. Their estimates and forecasts use the latest US Census Bureau Annual American Community Survey (ACS) as a starting point. They then combine additional data from multiple sources including residential postal delivery counts from the USPS; a time series of county-to-county migration patterns from the IRS; building permits; housing starts and local data sources that tested well against the most recent census.
