The Tobacco Use Supplement to the Current Population Survey (TUS-CPS) is a National Cancer Institute (NCI) sponsored survey of tobacco use that is administered as part of the U.S. Census Bureau's Current Population Survey. The Centers for Disease Control and Prevention (CDC) was a co-sponsor with NCI from 2001-02 through 2006-07.

The Tobacco Use Supplement-Current Population Survey (TUS-CPS) has served as a key source of national, state, and sub-state data on tobacco use behaviors, attitudes, and policies in the United States. The TUS is conducted every 3-4 years as part of the CPS, a monthly survey conducted by the U.S. Census Bureau for the U.S. Bureau of Labor Statistics. In each wave, TUS-CPS collects nationally representative data from about 240,000 adults, 180,000 from self-respondents. About two-thirds of respondents complete the questionnaire by telephone and responses for the remaining third are obtained through in-person interviews. The survey is regularly conducted in English and Spanish, and other languages when needed.

The project review timeframes above do not apply to applications that request access to confidential data assets commingled with data that are either not owned, or are only co-owned, by the statistical agency(s) or unit(s) and require approval from third parties not subject to this policy (e.g., state and local government agencies).

The National Longitudinal Mortality Study (NLMS) consists of a database developed for the purpose of studying the effects of demographic and socio-economic characteristics on differentials in U.S. mortality rates. The NLMS is a unique research database in that it is based on a random sample of the non-institutionalized population of the United States. It consists of Annual Social and Economic Supplements which cover the period from March 1973 to March 2011, Current Population Surveys for February 1978, April 1980, August 1980, December 1980, and September 1985, and one 1980 Census cohort, 39 cohorts in all. These are combined with death certificate information to identify mortality status and cause of death. The study currently consists of approximately 3.8 million records with over 550,000 identified mortality cases. This project has generated over 90 publications in various prominent scholarly, scientific, and public health related journals.

The MDAC is a study developed to estimate the effects of demographic and socio-economic characteristics on differentials in U.S. mortality rates. These objectives are achieved through record linkage of the large, nationally representative, 2008 American Community Survey (ACS) with mortality outcomes derived from the National Death Index (NDI) housed at the National Center for Health Statistics (NCHS) and Medicare/Medicaid information obtained from the Centers for Medicare and Medicaid Services (CMS). The database also includes data on local neighborhood and environmental characteristics such as: parks and recreation, crimes, hospitals and medical care facilities.  The MDAC database currently consists of approximately 4.5 million person records with over 308,000 mortality cases identified between the years 2008 and 2015. 

The MDAC is based on a complex, stratified sample of the 2000 Master Address File, therefore, it represents the population of the United States. The MDAC database currently consists of approximately 4.5 million person records with over 308,000 mortality cases identified between the years 2008 and 2015. The demographic and socio-economic variables from the ACS offer researchers the potential to answer questions on mortality differentials for a variety of important subgroups not covered as extensively in other databases.

The MDAC is designed to enhance previous research by not only ascertaining the independent contributions of person-level and neighborhood characteristics, but will allow exploration of interactions across a broad spectrum of mortality causes. This research may be used for informing policy makers and by scientists designing clinical trials targeting interventions in population subgroups defined by both neighborhood and person-level traits. The design of the MDAC also allows researchers to address questions concerning public health. In addition to its large size and comprehensive information on individual socio-economic characteristics, detailed geography (county, tract, and block level) is available on the ACS allowing linkage to standard census neighborhood characteristics such as median income, poverty rates, education, and multi-unit housing. Linkage opportunities also include area resources such as local and state parks, neighborhood traffic density, fast food restaurant density, and healthcare facilities. The ACS is one of the few surveys, due to its large sample size, permitting examination of not only person-level and neighborhood characteristics, but their interaction as well. Linkage to CMS Medicare and Medicaid data expand the possibilities of research to include morbidity outcomes and healthcare utilization among the elderly and poor. The 2008 ACS has over 700,000 respondents aged 65+ of which 575,000 indicate Medicaid as a source of health insurance.

The Administrative Data Research Facility (ADRF) is a secure cloud-based computing platform designed to promote collaboration, facilitate documentation, and provide information about data use to the agencies that own the data. The ADRF has provided secure access to over 100 confidential government datasets from 50 different agencies at all levels of government. More information on ADRF is available at https://coleridgeinitiative.org/adrf/.

Remote access to restricted-use data at the authorized licensed location via the the Administrative Data Research Facility (ADRF) by a connected, networked computer.  

Researchers may access restricted-use National Center for Health Statistics (NCHS) data at Research Data Centers (RDCs) located in Hyattsville, MD, Atlanta, GA, Rockville, MD, and Washington DC (government employees only). The NCHS RDCs are open by appointment only during regular business hours. The NCHS RDC computers are not connected to the Internet, and they have standard statistical software. An RDC Analyst will review all materials brought into the RDC and will review any notes, code, or output the researcher may want to take out of the RDC. Electronic devices (e.g., cell phones and laptops) are not permitted in the RDC. Some NCHS projects are authorized to access NCHS data at Federal Statistical RDCs (FSRDC). Non-US Citizens: In general, non-US citizens are not granted access to NCHS RDCs and are encouraged to use Federal Statistical RDCs to access restricted-use NCHS data.

Access via physical data enclaves in Atlanta, GA; Hyattsville, MD; Rockville, MD; or Washington, DC (government employees only).

NCSES Secure Data Access Facility (SDAF) houses NCSES restricted-use data and provides secure remote access to researchers. After researchers have submitted a restricted-use data application, received approval from NCSES, and have been trained on how to use the SDAF, they can login using an approved computer and a private internet connection. Each researcher has access to their own, personal file space and to a suite of software that can be used to store, access, and analyze data. For more information on accessing NCSES restricted-use data, please visit https://ncses.nsf.gov/about/licensing.
