Comment on Show HN: I built an interactive map and search engine for US Census data

Comments

The query engine doesn't understand the area of a state/county/zipcode(/census tract), unlke the official Census viewer https://www.census.gov/library/visualizations/2021/geo/demog...

When I query for "population density" I only get tables of total population. Not "people/sq mile".

Also, the default legend breaks are exponential (good) but not rounded to nearest n significant figures. And the color scheme is monochome green (hard to quickly read the map).

Thanks for trying it out - adding land area and supporting queries like "population density" will definitely be doable, and I'd like to make the legend and map color scheme a bit better (and ideally user-configurable) as well.

Really appreciate the feedback!

Uhuh. So when I query for "counties with highest population density", that specifies both the table and the geographical unit. (But currently that gives "B26001_001E: Group Quarters Population (Population in group quarters): Total")

I just made an update which should enable "population density" type queries to work a bit better - there is now an option to divide by 'LAND_AREA' for any variable (though this should probably be limited a bit), and this option will be automatically selected for queries including 'density' or a few related strings e.g. 'per sq. mile'
