I'm trying to find the population of Lyndonville NY on the census site. According to Wikipedia: Wiki_link "The population was 838 at the 2010 census." How do I find that on the census site?
Wikipedia gives this reference: https://www.census.gov/programs-surveys/decennial-census.html. If I go to this site, I can find data that goes down to the county level. But, I'm looking for data more specific. Could you tell me where on census.gov that I can find it?
I would recommend treating Wikipedia as more of a way to become aware of subjects than a source of accurate, up to date references. Wikipedia can be very good, but it is highly variable in quality.

. I'm going to answer your Van Nuys CA question here. The Web page that I gave you a link to gives their methods which you can program yourself once you have a shape file for Van Nuys. I was not able to find a shape file for that neighborhood but if you email Los Angles county you can probably get an "official" shape file. Then sum up the tract populations for tracts that are inside the neighborhood boundary. For tracts that span the boundary use the proportion (by area) of the tract population that falls inside the "official" boundary given by the Los Angles County map/shape file.
I use R which uses the libgeos C++ library (open source) https://libgeos.org/ (R rgeos and sf packages) It computes intersections, areas etc etc.s
