Census Bureau plans to stop production of 3-year ACS data

Mark Mather over 9 years ago

The Census Bureau is planning to discontinue the production of all 3-year ACS data, according to their 2015 budget justification document:

"The Census Bureau proposes to terminate permanently the “3-Year Data” Product. The Census Bureau intended to produce this data product for a few years when the ACS was a new survey. Now that the ACS has collected data for nearly a decade, this product can be discontinued without serious
impacts on the availability of the estimates for these communities."

There have also been some emails circulating that mention the 2015 ACS Data Users Conference has been canceled but I want to assure everyone that this is not the case!

It is worth noting that the concerns about margin-of-error on the 5-year products are more a problem of population and sample size for small jurisdictions, and less a problem of the 3-year versus 5-year aggregations.

Larger sample size might allow the Census Bureau to provide finer geographic detail in the 1-year products and would surely improve accuracy in the 5-year.

And (in reply to Oleh) - the Census Bureau just completed an exercise to investigate eliminating questions. That has a much broader impact and is generally not well received in the data user community. Every question has an important purpose.
