BETA-Time Series International Trade: Monthly U.S. Imports by Department of Agriculture Code

Data provided by  United States Census Bureau

The Census data API provides access to the most comprehensive set of data on current month and cumulative year-to-date imports broken down by agricultural and nonagricultural commodities. The USDA endpoint in the Census data API provides value, shipping weight, and method of transportation totals at the district level for all U.S. trading partners. The Census data API will help users research new markets for their products, establish pricing structures for potential export markets, and conduct economic planning. If you have any questions regarding U.S.

Data from Influence of Fire on the Lateral Resistance of Cold-Formed Steel Shear Walls - Phase 2

Data provided by  National Institute of Standards and Technology

Twenty-two 2.7 m by 3.7 m shear wall specimens consisting of 150 mm wide CFS framing were tested. All walls were designed to achieve a 1-hour fire-resistance rating per American Society for Testing and Materials (ASTM) standard E119. Heating was applied to the side of the wall opposite to the side where the shear-resisting elements are located; it is assumed that the shear-resisting elements line an egress corridor and the fire occurs in a room adjacent to the corridor.

Digital Library of Mathematical Functions

Data provided by  National Institute of Standards and Technology

The Digital Library of Mathematical Functions (DLMF) is an online reference on the properties of the special functions of applied mathematics. It contains three methodological chapters and 33 chapters focused on individual classes of functions. Information on functions include definitions, notations, series expansions, integrals, connection formulae, asymptotics, special values, methods of computation, etc. It includes hundreds of visualizations of the functions, including interactive three-dimensional representations of complex-valued functions.

Vintage 2018 Population Estimates: Characteristics by Single Year of Age

Data provided by  United States Census Bureau

Annual Resident Population Estimates by Single Year of Age, Sex, Race, and Hispanic Origin // Source: U.S. Census Bureau, Population Division // Note: 'In combination' means in combination with one or more other races. The sum of the five race-in-combination groups adds to more than the total population because individuals may report more than one race. Hispanic origin is considered an ethnicity, not a race. Hispanics may be of any race. Responses of 'Some Other Race' from the 2010 Census are modified.

2003 County Business Patterns: Business Patterns

Data provided by  United States Census Bureau

County Business Patterns (CBP) is an annual series that provides economic data by industry at the U.S., State, County and Metropolitan Area levels. This series includes the number of establishments, employment during the week of March 12, first quarter payroll, and annual payroll. CBP provides statistics for businesses with paid employees for the U.S., Puerto Rico, and the Island Areas. Census Bureau staff identified a processing error that affects selected data from the 2014 County Business Patterns (CBP).
