  "field": "Economic statistics",
  "definition": "During the ACS weighting process, the official county-level population and housing unit estimates are used as controls. Weights are adjusted so that ACS estimates conform to these controls. This is done to improve person and housing unit coverage and to reduce the variability of the ACS estimates. Total population and total housing unit estimates are controlled for states and counties. Combinations of age, sex, and Hispanic origin may also be controlled. Controlled estimates are by definition fixed, and are not subject to sampling error.",
