Projected Population by Single Year of Age, Sex, Race, and Hispanic Origin for the United States: 2012 to 2060 File: 2012 National Population Projections Source: U.S. Census Bureau, Population Division Release Date: December 2012 NOTE: Hispanic origin is considered an ethnicity, not a race. Hispanics may be of any race. The projections generally do not precisely agree with population estimates available elsewhere on the Census Bureau website for methodological reasons.

This Standard Reference Material (SRM) is intended for use as an analytical standard of known purity. It is intended primarily for use in the calibration and standardization of procedures for potassium (K) and chloride (Cl-) determinations employed in clinical analysis, including those using ion-selective electrodes, and for routine critical evaluation of the daily working standards used in these procedures. This lot of potassium chloride (KCl) was prepared to ensure a material of high purity and homogeneity and has been assayed after heating at 110 degrees C to 120 degrees C.

This web application provides free and open access to literature information contained in the NIST SOURCE Data Archive, and provides an easy-to-use tool for generation of a NIST Literature Report in PDF format, as required by the Journals. The tool is intended to aid researchers and reviewers in determining relevant literature sources for a given experimental measurement; however, it is not intended to replace the comprehensive literature review required by all journals, and no guarantee is made regarding completeness of the information provided.

This dataset consists of the XML schema for the NIST 1500-100 Election Results Reporting Common Data Format Specification Version 1.0.

Data from NIST TN 2006 'Interlaboratory mechanical-property study for Cobalt-Chromium alloy made by laser powder-bed-fusion additive manufacturing' DOI: 10.6028/NIST.TN.2006. Data from Figures 2, 3, 4, and 6, and Table 4.

Distributes NIST estimate of official U.S. time over the Internet in real time, using Network Time Protocol (NTP) and other time data formats to automatically synchronize clocks in computers and network devices to official U.S. time as realized by NIST several billions of times per day. This official U.S. time is the NIST estimate of Coordinated Universal Time (UTC), and called UTC(NIST).

Sulfonephthalein pH indicator dyes have historically been noted for impurities originating from the synthesis process which lead to batch to batch differences in pH measurements. Uncertainties up to 0.1 pH units have been attributed to impurities in these reagents.

This dataset provides the NIST Software Assurance Metrics And Tool Evaluation (SAMATE) Software Assurance Reference Dataset (SARD) - a set of programs with known security flaws. This will allow end users to evaluate tools and tool developers to test their methods.

Annual Estimates of the Resident Population by Single Year of Age and Sex for the United States // Source: U.S. Census Bureau, Population Division // Note: The estimates are based on the 2010 Census and reflect changes to the April 1, 2010 population due to the Count Question Resolution program.// For detailed information about the methods used to create the population estimates, see http://www.census.gov/popest/methodology/index.html.

Annual County Resident Population Estimates for 5 Race Groups (5 Race Alone or in Combination Groups) by Selected Age Groups, Sex, 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 groups adds to more than the total population because individuals may report more than one race. The estimates are based on the 2010 Census and reflect changes to the April 1, 2010 population due to the Count Question Resolution program and geographic program revisions.
