Analyze Census Data

[MicheleTobias]

Once the variables are identified, we need to run the analysis with the census data to understand the characteristics of the people inside and outside the access polygons.

We need to:

• [ ] Create a workflow for the analysis
• [ ] Implement the workflow

A useful document from Sebastian about the Census API which might also apply to the TidyCensus package: https://www.census.gov/content/dam/Census/library/publications/2020/acs/acs_api_handbook_2020_ch02.pdf

@alisonsnwong the estimate_population.R file is throwing an error for me in the read_census_variable_csv() function. On line 38, it throws an error trying to get the decennial census data. I thought it might be that my R session was giving me trouble setting my API key, so I tried it hardcoded into the request, but that didn't fix it. I'm going to try updating my R version to see if that's it.

This is the error:

Error in `stop_rate_excess()`:
! Request failed after 3 attempts

@MicheleTobias Hmm is the csv you are using the same as the current version on GitHub? I updated some of the column names and census variables because there were typos.

[MicheleTobias]

That might be it. I'm using the csv that's in the estimate_population branch.

What's the status of the code for analyzing the census data? It should output

• [x] A summary table of total populations inside and outside the isochrone boundaries
• [x] A vector dataset with the spatial data and the attributes, not repeating the geometies, but having a set of values for each polygon (e.g. each income class as a column, and race designations as their own columns, etc.)
