American Community Survey (ACS)
The American Community Survey is a new approach for collecting accurate, timely information needed for critical government functions. This new approach provides accurate, up-to-date profiles of America's communities every year. The American Community Survey will provide estimates of demographic, housing, social, and economic characteristics every year for all states, as well as for all cities, counties, metropolitan areas, and population groups of 65,000 people or more.

American Housing Survey (AHS)
The American Housing Survey (AHS) collects data on the Nation's housing, including apartments, single-family homes, mobile homes, vacant housing units, household characteristics, income, housing and neighborhood quality, housing costs, equipment and fuels, size of housing unit, and recent movers. National data are collected every other year, and data for each of 46 selected Metropolitan Areas are collected about every four years, with an average of 12 Metropolitan Areas included each year. The national sample covers on average 55,000 homes. Each metropolitan areas sample covers 4,800 or more homes.

Behavioral Risk-Factor Surveillance System (BRFSS)
The behavioral risk-factor surveillance system (BRFSS) operated for its second year in 1985. BRFSS data were collected from adults in 21 states and the District of Columbia by monthly telephone interviews with use of random-digit-dialing techniques. The interviews were conducted with a standard questionnaire and procedures developed jointly by the state health departments and CDC. The risk factors assessed included self-reported overweight, sedentary lifestyle, uncontrolled hypertension, cigarette smoking, alcohol misuse, and seat belt nonuse for persons 18 years of age and older (Tables 1 and 2). The results presented here are weighted to take into account the age, race, and sex distribution of adults in each state, as well as the respondents' probability of selection, and are therefore representative of the adult populations of the participating states.

Consumer Expenditure Survey (CES)
The Consumer Expenditure Survey (CES) program consists of two surveys—the quarterly Interview survey and the Diary survey—that provide information on the buying habits of American consumers, including data on their expenditures, income, and consumer unit (families and single consumers) characteristics.

County Business Patterns (CPB)
County Business Patterns (CBP) is an annual series that provides subnational economic data by industry. The series is useful for studying the economic activity of small areas; analyzing economic changes over time; and as a benchmark for statistical series, surveys, and databases between economic censuses. Businesses use the data for analyzing market potential, measuring the effectiveness of sales and advertising programs, setting sales quotas, and developing budgets. Government agencies use the data for administration and planning.

County Business Patterns covers most of the country's economic activity. The series excludes data on self-employed individuals, employees of private households, railroad employees, agricultural production employees, and most government employees. The County Business Patterns program has tabulated on a North American Industry Classification System (NAICS) basis since 1998.

It is also used to draw the lines of legislative districts and reapportion the seats each State holds in Congress. DataFerrett offers the data for the following Census products:
  • Census 2000 Summary Files 1 & 3
  • Census 2000 Public Use Microdata Sample (1%)
  • Historical Census Data from IPUMS

National Ambulatory Medical Care Survey (NAMCS)
The National Ambulatory Medical Care Survey (NAMCS) is a national survey designed to meet the need for objective, reliable information about the provision and use of ambulatory medical care services in the United States.

This is one of the few sources of comparable health-related data for small geographic areas and a long time period in the United States. The data are also used to present the characteristics of those dying in the United States, to determine life expectancy, and to compare mortality trends with other countries. Preliminary and final annual data are available.

National Health Interview Survey (NHIS)
Information is collected on all household members. A household adult reports information for a randomly selected child less than 18 years of age in the Child Core questionnaire, and a randomly selected adult reports for him/herself in the Adult Core questionnaire. Questions are designed to retain comparability to previous NHIS surveys for reporting of activity limitation due to physical, mental, or emotional problems. Information on activity limitation is collected on each family member.

National Hospital Ambulatory Medical Care Survey (NHAMCS)
The National Hospital Ambulatory Medical Care Survey (NHAMCS) is designed to collect data on the utilization and provision of ambulatory care services in hospital emergency and outpatient departments. Findings are based on a national sample of visits to the emergency departments and outpatient departments of noninstitutional general and short-stay hospitals, exclusive of Federal, military, and Veterans Administration hospitals, located in the 50 States and the District of Columbia. The survey uses a four-stage probability design with samples of geographically defined areas, hospitals within these areas, clinics within hospitals, and patient visits within clinics. Annual data collection began in 1992.

National Survey of Fishing, Hunting and Wildlife-Associated Recreation (FHWAR)
Presents microdata records (with any information that might identify a specific person or household removed) on individuals involved in fishing, hunting, and other wildlife-associated recreation, such as wildlife observation, photography, and feeding. Data include state in which these activities occurred; number of trips taken; duration of trips; and expenditures for food, lodging, transportation, and equipment.

New York City Housing and vacancy Survey (NYCHVS)
The 2008 survey, which reveals a synopsis of the City's housing market between February and June 2008, found that the citywide net rental vacancy rate was 2.88 percent, down from 3.09 percent in 2005. The City's total housing stock rose to more than 3.33 million units, the largest in the 43-year period since the first survey was conducted in 1965, and all five boroughs saw an increase in housing. New Yorkers' satisfaction with their neighborhoods and overall building conditions reached their highest ever levels since they were first measured, 30 years ago and 43 years ago, respectively. The survey, conducted every three years, is required by State and City rent-regulation laws to determine New York City's overall vacancy rate for rental housing.

Small Area Health Insurance Estimates for Counties and States (SAHIE)
The Census Bureau's Small Area Health Insurance Estimates (SAHIE) program produces estimates of health insurance coverage for states and all counties.

In October 2008, SAHIE released 2005 estimates of health insurance coverage by age, sex, race, Hispanic origin, and income categories at the state-level and by age, sex, and income categories at the county-level.

Small Area Income & Poverty Estimates for School Districts, Counties, and States (SAIPE)
The U.S. Census Bureau, with support from other Federal agencies, created the Small Area Income and Poverty Estimates (SAIPE) program to provide more current estimates of selected income and poverty statistics than those from the most recent decennial census.
Estimates are created for school districts, counties, and states. The main objective of this program is to provide updated estimates of income and poverty statistics for the administration of federal programs and the allocation of federal funds to local jurisdictions. Estimates for 2006 and 2007 were released in December 2008. Beginning with the estimates for 2005, data from the American Community Survey are used in the estimation procedure; all prior year estimates used data from the Annual Social and Economic Supplements of the Current Population Survey.
