The FY 2011 PLS report will be released in the early fall.
Note From Deanne Swan, IMLS Senior Statistician (via E-Mail):
The full file (AE and outlet) was re-geocoded using the most current mapping technology. This included not only updates to latitude and longitude fields, but also the addition of a new field with information on metropolitan/micropolitan status. Justin Grimes, IMLS Statistician, and I are also working on a data note to provide information about the effect of these updates, including how many records saw a change from the original FY 2008 coding and, if there was a change, the magnitude of that change. As noted in the data documentation, most entities (81% of AEs and 75% of outlets) saw little (less than 50 feet) or no change to their LAT-LONG positions, suggesting that the precision was already very high for most entities. The data note will articulate this in more detail.
