I see from https://en.wikipedia.org/wiki/Van_Nuys that "The 2000 U.S. census counted 136,443 residents in the 8.99-square-mile Van Nuys neighborhood". Could you tell me where I can see that on the census site and download that data? I was hoping wikipedia included the reference on census.gov where that information is located, but it does not.
Thanks
Okay, get ready go down a rabbit hole...As David Dorer noted, Van Nuys is a neighborhood, not officially recognized by any federal entity and no Census statistics are reported for it.If you want "official" demographics for neighborhoods, your best source is usually the city is which the neighborhood is located. They keep track of the geographic boundaries and usually have a collection of statistics which are more or less useful.
In the case of Van Nuys, the city of Los Angeles has this data for viewing and download...https://data.lacity.org/Community-Economic-Development/Census-Data-by-Neighborhood-Council/nwj3-ufba"Census Data by Neighborhood Council""Census 2010 population/demographic data approximated from block groups to LA Neighborhood Councils using Esri software"
