What are ZCTA’s?

The 2010 Census doesn’t use zipcodes, it uses ZCTA’s (zip code tabulation area) which makes counting easier for the tabulators. ZCTA’s are the same as zipcodes for 99.9% of the data (in other words, a very small number of houses will be represented by a different zipcode). This is simply because some locations have multiple zip code per block, which makes it hard for the census. For most cases this has no effect on the accuracy of the data and can be used interchangeably with zip codes. In fact, the Census Bureau provides ZCTAs for the purpose of zip code statistics.
