In today's media release the Census Bureau announced its upcoming
schedule for product distribution. In it were some "new" products
that may be of interest to people on this list. I will highlight a
few below. Here is the link to the entire media release .
http://www.census.gov/newsroom/press-releases/2016/cb16-101.html
In December we will see our first release of two non-overlapping
5-year ACS data sets (2006-2010, and 2011-2015) .
On Thursday, July 21, 2016 we will see several "NEW" products.
1. 2014 Supplemental Estimates: This new product will consist of 58
detailed tables tabulated on the 2014 one-year microdata for
geographies with populations of 20,000 or more.
These supplemental estimates will be released on American FactFinder
and the Census Bureau’s application programming interface, and will
be available for the same geographic summary levels as those in the
American Community Survey 1-year dataset.
2. Statistical Testing Spreadsheet : This ACS statistical comparison
tool will allow users to carry out statistical testing for two or
more ACS estimates using the margin of error to determine whether
the estimates are significantly different (higher or lower) from
each other or are not significantly different (statistically tied)
from each other. In our CTPP world we also know of two other tools.
One developed by the NY State Data Center
(https://sdcclearinghouse.wordpress.com/2009/03/03/spreadsheet-to-calculate-acs-margins-of-error-and-statistical-significance-for-sums-proportions-and-ratios/)
and another one developed by CUTR at the University of South Florida
(http://www.nctr.usf.edu/abstracts/abs77802.htm).
3. 2010-2014 replicate tables: This new product will provide
expanded versions of 107 detailed tables that are published in
American FactFinder. In addition to the published estimates and
margins of error, 80 replicates for variance calculations are also
provided. This product is intended for advanced users and will allow
them to calculate the margins of error when aggregating across
geographies or collapsing categories within tables without using
approximation formulas. The replicate tables will be released on the
FTP site with links available on American FactFinder.
