Well, the newest news is that Census 2020 PL94-171 data is re-scheduled for release this coming Thursday, August 12th. Hope everyone is ready.

I did a lot of messing around with the R package TIGRIS this past spring. I’m not sure why I didn’t share it at that time, but here it is now. Hope it helps.

from the author’s page:

tigris is an R package that allows users to directly download and use TIGER/Line shapefiles (https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html) from the US Census Bureau.

Here is Kyle Walker’s March 2021 lecture on “Spatial Analysis of US Census Data” on youtube.com. Watch it!

TIGRIS is working and ready for Census 2020 geographies!! So when the PL94-171 data is available this coming Thursday, I’m expecting a lot of people to get really busy with it!

(Refer back to my 7/23/21 post regarding the R package PL94171. My next example might be some stitching the TIGER files with the PL 94-171 demographic data!)

I’m attaching two of my R scripts that test a ton of the capability of TIGRIS. I’m not “attaching” any demographic data to the geographic layers, just yet. The purpose here is to get a hold of these TIGER/Line shapefiles, and get ready for newer (or older) census data from the decennial census or the American Community Survey.

My Part I script includes the following examples:

# 1.1 -- County Boundaries in California (Detailed TIGER/Highest Resolution)

# 1.2 -- Exporting SHP files to a local computer drive

# 2 -- County Boundaries in California (Medium Resolution)

# 3 -- County Boundaries in California (Lowest Resolution)

# 4.1 -- Tract Boundaries for One County

# 4.2 -- Tract Boundaries for One County, Multiple Census Years (1990-2020)

# 5 -- Tract Boundaries for Multiple Counties in a State

# 6 -- Block Group Boundaries for Multiple Counties in a State

# 7 -- Block Boundaries for Multiple Counties in a State

# 8 -- Place Boundaries within a State

# 9 -- PUMA Boundaries within a State

# 10 -- Consolidated Statistical Areas in the USA

# 11 -- Core-Based Statistical Areas in the USA

# 12 -- Congressional Districts in the USA, single state, and filtering states

# 13 -- Urbanized Areas in the USA

# 14 -- State Legislative Districts (Upper/Lower House) for a State

# 15 -- Zip Code Tabulation Areas, Selected for a State and within state

# 16 -- State Boundaries in the USA

My Part II script includes the following examples:

# 1 -- Roads for Counties, Multiple Counties within State

# 2 -- Primary & Secondary Roads within a State

# 3 -- Rails for the USA

# 4.1 -- Water Areas for Multiple Counties within a State

# 4.2 -- Water Lines for Multiple Counties within a State

# 5 -- Point & Area Landmarks within a State

That’s all for now. Happy Saturday afternoon, and IPA Day!
