The Current Population Survey (CPS) is a monthly survey of about 50,000 households conducted by the Bureau of the Census for the Bureau of Labor Statistics. The survey has been conducted for more than 50 years. The CPS is the primary source of information on the labor force characteristics of the U.S. population. The sample is scientifically selected to represent the civilian noninstitutional population. Respondents are interviewed to obtain information about the employment status of each member of the household 15 years of age and older. However, published data focus on those ages 16 and over. The sample provides estimates for the nation as a whole and serves as part of model-based estimates for individual states and other geographic areas.

The Center for Environmental Information and Statistics (CEIS) EPA has assessed major EPA databases to characterize their overall quality and applicability for non-programmatic and secondary uses such as evaluating the local state of the environment, identifying pollution sources and hot spots, promoting environmental education, and tracking corporate accountability. The assessment process resulted in descriptions of each of the major databases that include information on coverage, spatial characteristics, temporal characteristics, consistency within the data system, ability to link to other systems, accuracy, limitations, access, and documentation.

The Geography and Map Division (G&M) has custody of the largest and most comprehensive cartographic collection in the world with collections numbering over 4.5 million maps including 60,000 atlases, 6,000 reference works, numerous globes and plastic relief models, and a large number of cartographic materials in other formats, including electronic. These cartographic materials date from fourteenth century portolan charts through recent geographic information systems data sets. The Reading Room provides in-person, telephone, and written reference assistance to Congress, Federal agencies, state and local governments, the scholarly community, and the general public.

The GNIS Feature Names Data Base contains records on almost 2 million geographic features in the United States-- from populated places, schools, reservoirs, and parks, to streams, valleys, springs, and ridges. The data base is being compiled in two phases. The first phase is complete for all States and areas under U.S. jurisdiction and included the collection of most feature names found on the 1:24,000-scale maps published by the USGS, as well as names on Office of Coast Survey charts, U.S. Forest Service maps, and in data files of the Army Corps of Engineers, the Federal Aviation Administration, and the Federal Communications Commission. The second phase of compilation is on-going, and involves the collection of current and historical names from official State publications and local materials.

Through computer processing and enhancement, we have brought together two existing images of the Nation's lower 48 states into a single digital tapestry. Woven into the fabric of this new map are data from previous U.S. Geological Survey (USGS) maps that depict the topography and geology of the United States. The resulting composite is the most detailed and accurate portrait of the U.S. land surface and the ages of its underlying rock formations yet displayed in the same image.

The Operational Significant Event Imagery team produces high-resolution, detailed imagery of significant environmental events which are visible in remotely-sensed data available at the NOAA Science Center in Suitland, Maryland. Our Daily Operational Significant Event Imagery Report (DOSEIR) outlines the events we have captured in satellite imagery and provides a direct link to each image. The images are described with short narratives. This report is available Monday through Friday as an email via subscription or on this website in a remote window.
