The Bureau didn't publish ACS data for ZIP Code Tabulation Areas (the level most closely matching "ZIP codes") until the 2011 release. This page lists which areas are identified in the 2009 release. You can click on other tabs there to see what…
The Census Bureau does not produce population data at the Zip Code level, but rather by the Census Bureau's own Zip Code Tabulation Areas, or "ZCTA." If you are wondering what a ZCTA is, watch this quick explanation and how they compare to zip codes…
I don't believe ZCTAs cover the entire country.It's definitely not based on the respondents' ZIP; ZCTAs are explicitly different than mailing zip codes, based on coordinate location, not address.
I'm looking at the 5-year estimate data for a specific zip code and analyzing population by age. Specifically, I'm looking at the population changes in the 0-4 year old and 5-9 year old populations. The analysis that I'm attempting to complete…
This is true but there are many cases where zip code is important in itself. Change of address and real estate data is often aggregated that way. And the truth is, your house is worth more or less in some zip codes so it makes sense
That makes perfect sense - thank you!
BTW, how do you know this? I searched the docs and couldn't find any explanation except the one source I quoted, which was wrong.
PS: I've confirmed it is count of households. For every zip code, multiply B19001_001E…
I'm trying to merge zip codes so the the combined area has a population of 20,000 or more. I'm trying to de-identify a data set that has zip codes by merging adjacent ZCTAs.
If you have any ideas let me know. Perhaps someone has already done this…
Cliff,
We've got land and water areas (and populations, and therefore densities) for every state, county, metro, city, cosub, and zip code.Shoot me an email and I'll hook you up.Bertbert@bestplaces.net
Yes I did something like this here for zip code and for income I just grabbed household income by race to see if the effect was different in higher-income Black areas (not really) -- zip code is not an optimal geography but some of my examples in suburban…
