  • RE: Household Pulse Survey

    Beth Jarosz
    Beth Jarosz

    What do you mean by maximize data analysis? Do you mean reduce the margins of error? If so, pooling across multiple weeks is one way to increase sample size and improve reliability of estimates...

  • RE: Getting a list of zip codes in federally recognized Native American/American Indian reservations

    Joe Germuska
    Joe Germuska
    That is quite strange! In general, I've found the native american geographies confusing and hard to find documentation about.

    I did find one Wyoming reservation, Wind River, which comes up in the X-walk. It seems to be the only reservation known…

    For how to compute the MoE (Margin of Error) for a %.   Note these formulas are approximate and need some adjustment near 0 or 100 %

  • RE: Error in sequence file or table shells file for 2013?

    Joe Germuska
    Joe Germuska
    Glenn, thanks for creating that.

    I've had a pretty busy fall, and it seemed to make sense to wait until everyone has had a chance to deal with all of this year's data, so I was thinking that I'd start connecting people to talk in January.

  • RE: Querying 2020 5 year estimate detailed table giving null values.

    Diana Lavery

    Hi Spence, looks like you're getting nulls for the fields that end in EA (estimate annotation) and MA (margin of error annotation) which are essentially the footnotes when there are asterisks or other symbols in the table instead of numbers. This table…

  • RE: Workflows for combining ACS geographies

    David Dorer
    David Dorer

    Dear Steve,

    Don't forget that the ACS is a survey and the numbers in the tables are survey/sample estimates. A census is a count of "everybody" and there is no "margin of error"

    As a general matter you can look at tract level estimates…

    Hi Jennifer,
    The usual guidance from the Census Bureau is to use ACS for share of population or rates (i.e. percent of the population who are children, poverty rates, etc.) and the 2020 Census for population totals. The 2020 Census does not have a margin…

  • RE: Multiple regression model with unemployment proportion as response

    Aggregating the data to larger geographic areas is one potential solution if you are encountering large margins of error or zero values. Seth Spielman also described some potential strategies/pitfalls related to data aggregation in a 2015 paper:

  • RE: 2020 ACS 5 Year estimates

    Beth Jarosz
    Beth Jarosz

    Hi Liliam -

    In a typical year there is not much change from one 5-year ACS estimate to the next because 4 of the 5 years are the same (data for 2016, 2017, 2018, and 2019 show up in both the 2019 5-year and 2020 5-year). In addition the number of households…

  • RE: De-identify ZCTA based data

    Dave Stinchcomb
    Dave Stinchcomb

    Interesting David. 

    There are some existing tools that combine adjacent geographic areas to meet various objective functions (minimum population, minimum margin of error, etc.).  Some try to combine areas that are homogeneous by some attribute (demographics…
