When the Census Bureau conducts a census for a city like North Buena Vista, they draw a boundary around the area in which they are going to conduct their count - this defines the sampling area (usually shaped as a polygon).

Things like the population, area and housing for North Buena Vista reflect the sampling area. Since the shape of the sampling area and the actual boundaries of North Buena Vista might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.

Census ZCTA Codes ...
The US Census Bureau created statistical entities that they call ZIP Code Tabulation Areas (ZCTAs) and these ZCTAs are frequently confused with the ZIP codes that come from the US Postal Service (USPS).
ZCTAs were first created for the 2000 Census and at that time, they were based upon the USPS ZIP codes. While largely covering the same areas, the boundaries of a ZCTA do not necessarily match the boundaries of a postal ZIP code with the same number. For example, while a postal ZIP code can cross a county or state line, a Census ZCTA can not. They should be treated as separate entities with no correlation between them.
