When the Census Bureau conducts a census for a town like Lockhart, 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). The shape of the sampling area can be quite complex and it's important to keep in mind that the boundaries of the sampling area may or may not match the recognized boundaries of the town.
Things like the population, area and housing for Lockhart reflect the sampling area. Since the shape of the sampling area and the actual boundaries of Lockhart might be different, it's best to check with the U.S. Census Bureau to resolve any difference between the two.
The 2010 Census shows that the sampling area for Lockhart has a total area of 1.13 square miles [2.9 km²]. Of this total, 1.09 square miles [2.8 km²] is land, with the balance (3.55%) being water (0.04 square miles [0.1 km²]).

Lat: 31° 0' 46" (or 31.01°) [Map]

This area (or sampling area) is a polygon and its shape can be quite complex - it may or may not match the geographical boundaries of Lockhart. It's important to note that from one Census to the next, the shape and location of the polygon can change. If you need precision or details about the methodology of the Census, you should visit the U.S. Census Bureau for a definitive answer.

Although the ZIP Code doesn't specifically identify a town like Lockhart, it does identify addresses that are in (or near) Lockhart. It's important to remember that the boundaries of a ZIP Code can be changed, re-assigned or overlapped with other ZIP Codes.

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.
