Where does the ZIP code ZCTA come from?
ZCTA is a trademark of the U.S. Census Bureau; ZIP Code is a trademark of the U.S. Postal Service. The Census Bureau first examined all of the addresses within each census block to define the list of ZIP Codes by block.
As only the intersections between the two entities are shown in the relationship file, the sum of the part columns for all records representing a specific ZCTA or metropolitan/micropolitan statistical area may not add up to the totals for the ZCTA or metropolitan/micropolitan statistical area.
What do ZCTAs stand for in the census?
For the Census 2000 ZCTAs the Census Bureau created ZCTAs that ended in “XX” to represent large areas of land without ZIP Codes or “HH” to represent large areas of water without ZIP Codes. For the 2010 Census, large water bodies and large unpopulated land areas do not have ZCTAs.
How does the relationship file work for ZCTA?
As only the intersections between the two entities are shown in the relationship file, the sum of the part columns for all records representing a specific ZCTA or place may not add up to the totals for the ZCTA or place. As Places are not wall-to-wall entities and do not cover the entire nation, this file may not contain all ZCTAs.
What’s the average age of the 65 and older population?
The 65-and-older population grew by over a third (34.2% or 13,787,044) during the past decade, and by 3.2% (1,688,924) from 2018 to 2019. The growth of this population contributed to an increase in the national median age from 37.2 years in 2010 to 38.4 in 2019, according to the Census Bureau’s 2019 Population Estimates.
What does the aging of the US population mean?
The aging of the population will have wide-ranging implications for the country. By “aging,” demographers often mean that the proportion of the population in the older ages increases. As the United States ages over the next several decades, its older population will become more racially and ethnically diverse.
