acs version 2.0: an R package to download and analyze data from the US Census

The package allows users to download, manipulate, analyze, and present

demographic data from the U.S. Census, with special tools and methods

to simplify the tasks of working with estimates and standard errors

contained in data from the American Community Survey (ACS).

Version 2.0 of the package provides full support for all ACS data

available through the Census API — including the most recent 2014

data — as well as Decennial Census Data from 1990, 2000, and 2010.

Users can work with existing census geographies (states, counties,

tracts, block-groups, places, zip code areas, congressional districts,

school districts, etc.), or create and save their own custom

geographies with the package’s “geo.make()” function.

Special thanks to package beta testers (Ari, Arin, Bethany, Emma,

John, and Michael) and the entire acs-r community, as well as to Uwe

and Kurt at CRAN for their infinite patience and continuing care and

stewardship of the system.
