trying to find the population of Van Nuys, CA

carljong2003

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

    The downside is that the "official" city statistics are based on 2010 Census numbers.
    But the "StatisticalAtlas" site is not that all up-to-date either.  A quick look at their population count for the 91405 zip code (54,356) shows their data is from the 2012-2016 5-year data set.  
    Also the neighborhood boundaries are at least ten years old, coming from a data set released into the public domain by Zillow about a decade ago and taken down about three years ago.

    I've chatted with Jim D the owner of the StatisticalAtlas site and have some insight into it.  
    Jim's a very skilled programmer and his small group have produced some cool sites (check out Weatherspark).  But their focus is on the business of attracting search results to their site and collecting the ad revenue.
    I wouldn't rely on it for timely demographics, but it does have a unique and useful way to look at the relationships between geographic boundaries.

    If it's helpful, Census Reporter developed a service to compute 2020 and 2010 population for neighborhoods and other local non-census geographies. All we need is a shapefile, or, preferably a pointer to a publicly accessible shapefile/geojson. If you provide us a link to a public map, we share the results publicly on https://censusreporter.org/2020/
    When we launched, it was self-service, but that was slightly bumpy, so it's by request now. No guarantees, but turnaround is generally within one business day, unless I'm on vacation :) The code is public on GitHub, but it basically works by assigning blocks to the user-provided geographies that contain each block's centroid/internal point. If the map aligns with a Census place, I also run a little audit process against the 2020 redistricting data population totals, and in the rare case that there's a serious mismatch, we include notes about it on the pages linked from above.
    A very brief look didn't turn up a straightforward GIS file for LA "neighborhood councils," but if you have them, use the link on the above page to submit a request.

    ah, I missed that we already have a tabulation for 318 "LA County Neighborhoods" (original map from UCLA, unfortunately returning a 500 error now)

    censusreporter.org/.../

    It lists the 2020 population of Van Nuys as 109,290 compared to 104,734 in 2010. I note that that's considerably higher than the 2010 population in the data.lacity.org, but again, the maps are likely not identical.

    Dear Joe,

    I was just about to ask for a link to the LA shape file !

    just found one on the LA county website:

    this may be a google-link

    https://geohub.lacity.org/datasets/d6c55385a0e749519f238b77135eafac_0/explore

    This came for the search box on the LA website

    https://geohub.lacity.org/datasets/neighborhood-council-boundaries-2018/explore

    Here is the LA data search page (Los Angeles GeoHub official data)
