Previous README for various census data:

• README.rst - this general ReadMe
• README.censusTract.rst - 1st round, replicating Bostock commands, pop density by Census Tract
• README.censusBlock.rst - 2nd round, pop density by Census Block Group (in CA Albers projection)
• README.lngLat.rst - 3rd round, variant of 2, without Albers projection, just use plain Longitude,Latitude coordinate
• README.lngLat2010BG.rst - 4th round, variant of 3, use Census 2010 data at block group level. have pop density, pop count and CENSUSAREA in final geojson
• README.lngLat2010Tract.rst - 5th round, variant of 3, use Census 2010 data at census tract level. have pop density, pop count and CENSUSAREA in final geojson
• README.devNote.rst - commands to aid in development.

• Census Estimate for 2018 (ACS survey, [5 year result?])
• Decenial Census survey 2010. Note that in 2014 API/fields changed compared to 2010, so round 3 vs 4+5 has slightly diff commands.
