When Houston was competing with a Brazilian city to be the site of a Japanese-owned plant, Houston could provide the Japanese with pertinent information about the educational attainments and other qualities of its workforce and the number of Japanese speakers in the area. The plant is in Texas partly because Houston had superior statistics, thanks to an inexpensive federal program currently under attack from some conservatives. They may not know that its pedigree traces to the Constitution's Framers.
These Enlightenment figures — rational, empirical, inquisitive — believed in the possibility of evidence-based improvements. And they mandated the “enumeration” of the population every 10 years. James Madison soon proposed expanding the census beyond mere enumeration to recording Americans' occupations. And compliance with the survey was compulsory.
During America's post-Civil War dynamism, President Ulysses Grant proposed a census every five years to keep government abreast of change. Beginning in 1940, a small percentage of households was required to fill out what came to be the “long form.” And since 2005, this has been replaced by the American Community Survey that about 3.5 million households a year are required to complete, providing demographic, economic and social information pertinent to government and private-sector activities.
The government still makes mandatory the mild duty of providing information pertinent to governance. This is why some conservatives oppose continuing the ACS. Distrust of the politicized IRS, with its mountains of sensitive information, and anxiety about the National Security Agency's collection of metadata have deepened Americans' instinctive suspicion of government, which is healthy. But the ACS should not become collateral damage.
If the survey were voluntary, compliance would plummet and the cost of gathering the information would soar. The data, paid for by taxpayers and available to them at no charge, serves what the nation needs most — economic growth. Target, Wal-Mart and other large retailers tailor their inventories to regional, even neighborhood differences revealed in the ACS' granular data. Homebuilders locate markets rich in persons 25 to 34, and renters.
