Timing for 2012-2016 five year dataset

When will the latest five year dataset be available?

The U.S. Census Bureau has scheduled the new 5-year public use file to be released on January 18, 2018. After this release it typically takes IPUMS USA a month or so to prepare the data for the IPUMS website. So, outside of any unexpected delays, you can expect the new 5-year file by early spring 2018.
