Has responsibility of conducting and supporting research on long-range problems of measurement of social and economic phenomena in censuses and surveys.

Conducts experiments to estimate the effects of response errors in analyzing census data.

Conducts experiments to estimate the effect of coders on the variability of census statistics.

By analyzing basic data, tries to formulate causes for the bias in statistics gathered from rotating panels and formulate methods to reduce these biases.

Produces mathematical models to investigate the problem of linking records from
two files or lists and formulates optimum decision rules.

The function of this laboratory is to provide support to the Census Bureau mission of
information gathering and dissemination, particularly in the processing of data from
censuses and surveys. In
In earlier censuses, this laboratory produced and maintained
specialized tabulating equipment (such as the Census unit counter and multi-column
sorter) and key punch devices. Principal current activities include:

Design and prototype development work on a variety of paper-handling devices. Experimental work with automatic paper-handling devices to speed up work processes. (14-05 Microfilm) (17-05 Optical Scanning)

To develop features expanding the usability of a commercial microfilm retrieval system, namely, film cartridge feeding; manual and automatic film-to-film copying; manual and automatic search code entry with checking for both alphabetic and numeric codes.

Carries out a program of theoretical and experimental research on boundary layer processes in the earth's atmosphere (04-02 Meteorology). The research emphasizes the problems of defining the dispersion of pollutants together with the application of numerical models to understanding diffusion processes (13-02 Air Pollution).

Meteorological support in connection with the various operations of the Atomic Energy Commission at the Oak Ridge National Laboratory is also provided.
