Good Ole Massachusetts. The apartment we rent (2nd floor of a house) was built in 1924. Same with the entire street really and all over.
Mother’s house in central MA was 1956
Data: American Community Survey accessed via API using tidycensus package in R
Tools: R
packages for data wrangling: dplyr, stringr
packages for mapping/shapefiles: colorspace, scales, sf, ggplot2, ggfx, grid, usmap, tigris (for PR shapefile)
packages for fonts: sysfonts, showtext
I know you’re going for an aesthetic, but in some smaller counties it’s hard to tell 70s or 80s.
Crazy that LA county is the 60s despite all the growth since then. Same thing with SF Bay. Absolutely crazy nimby problem in those areas
what is considered a housing unit? For example, does a building consisting of 100 apartments built in 1980 count as a 100 housing units built in 1980?
It’s breaking my brain the median is so old for the tornado alley.
It’s crazy how you can see the outline of the Houston and Dallas-Fort Worth metro areas.
Should change the color scale from red to green to show more contrast, with green being the most recent to show which areas are building adequate housing
Shit is so visibly old here in Pittsburgh it’s crazy. Is like being in a time capsule.
