Dear , I write to express my concern for the FY16 budgets for the U.S. Census Bureau in the House and Senate FY16 Commerce, Justice, Science appropriations bills and to urge the requested amount be enacted. I also want to urge you not to adopt the House provision to make the American Community Survey (ACS) voluntary. Full funding for the Census Bureau has the potential to save billions of dollars on the cost of the 2020 decennial census if sufficient investments are made now. The mandatory ACS helps to make government smarter and more efficient and also helps support economic growth and development in the United States. The House and Senate levels for the Census Bureau, $990 million and $1.13 billion, respectively, are well below the FY16 requested level, $1.50 billion. The Census Bureau requested a $410 million increase over the FY15 level, which tracks with past increases for this stage of the decadal census planning and preparation. The estimated cost for the 2020 Census, which assumes sufficient funding for its planning and preparation, is $13 billion, about the same as the 2010 census. While still a large cost, keeping the cost of the 2020 decennial at the same level as the 2010 census would be a remarkable achievement given two points: (i) 2011 GAO analysis warned the 2020 census could cost as much as $25-30 billion unless major design changes are made1; (ii) decennial census costs have been steadily increasing on a per-household basis because of the ever-growing complexities of a more diverse population and the increasing challenges of survey response.2 The potential to keep the cost of the 2020 Census level at the 2010 level is a result of the Census Bureau’s extensive reengineering of the decennial census and the Census Bureau but such savings can only be achieved with sufficient investment now for the various tests and work to be done. Removing the mandatory requirement for the ACS would significantly impact the quality and availability of the ACS data, which is frequently referred to as the gold standard. We know from many sources—U.S. Census Bureau research3, survey research, private sector experience, and Canada’s experience with converting their mandatory long-form census to a voluntary survey4—that, with a voluntary ACS, response rates would plummet from the high 90th percentile by at least 20-30 percentage points. To compensate for lower response rates, the likely consequences would be 1 More households would receive the survey in order to maintain number of respondents ACS households not responding to survey would likely experience more contact from Census Bureau urging them to respond The Census Bureau estimates that an additional $90-$100 million/year would be required to compensate for lower response rates5 “Census: Learning Lessons from 2010, Planning for 2020”, April 6, 2011 hearing of the Senate Homeland Security and Government Affairs Committee, http://www.hsgac.senate.gov/subcommittees/federal-financialmanagement/hearings/census-learning-lessons-from-2010-planning-for-2020 (minute 4x:yy) 2 http://www.gao.gov/assets/670/669768.pdf 3 http://www.census.gov/library/working-papers/2011/acs/2011_Navarro_01.html 4 http://www12.statcan.gc.ca/NHS-ENM/2011/ref/about-apropos/nhs-enm_r012.cfm?Lang=E 5 https://www.census.gov/programs-surveys/acs/methodology/mandatory-voluntary-methods.html Fewer respondents would result in lower quality data (i.e., larger margins of error and a less representative sample), likely resulting in no data being published at all for less populous areas.6 The absence of data for the more rural portions of the United States and lower quality data could undermine smart, efficient government and also hinder economic growth. Local, state, and federal government use ACS for a wide gamut of its work, from directing federal assistance7 to where it is most needed for insuring wise investments are made for such activities and infrastructure, services and disaster preparedness. The private sector uses these data to make sure their investments pay off, which means more jobs and tax revenue. In short, full funding for the U.S. Census Bureau and a mandatory ACS benefits this country immensely. 6 https://www.census.gov/programs-surveys/acs/methodology/mandatory-voluntary-methods.html Andrew D Reamer, “Surveying for Dollars: The Role of the American Community Survey in the Geographic Distribution of Federal Funds,” Brooking Institution, 2010: http://www.brookings.edu/reports/2010/0726_acs_reamer.aspx. . 7
