The data series can be obtained from the Federal Reserve Economic Database (FRED). As of October 2024, there were 269,300,000 persons in the civilian noninstitutional population [2] out of a U.S. population of 337,446,000 approximately. [3] It has steadily grown along with the U.S. population, roughly 1% per year for 2005-2013 period.
Employment status of the civilian noninstitutional population 16 years and over by age, sex, race, Hispanic origin, marital status, family relationship, and Vietnam-era veteran status. Employed persons by occupation, industry, and class of worker, hours of work, full- or part-time status, and reasons for working part-time.

A population is defined as a group of interacting organisms of the same species. A demographic structure of a population is how populations are often quantified. The total number of individuals in a population is defined as a population size, and how dense these individuals are is defined as population density.
Population density (in agriculture: standing stock or plant density) is a measurement of population per unit land area. It is mostly applied to humans , but sometimes to other living organisms too. It is a key geographical term.
Biological engineering is a science-based discipline founded upon the biological sciences in the same way that chemical engineering, electrical engineering, and mechanical engineering [7] can be based upon chemistry, electricity and magnetism, and classical mechanics, respectively.
All x from the survey are used to model how detectability decreases with distance from the transect, which allows estimation of total population density in the surveyed area. A common approach to distance sampling is the use of line transects. The observer traverses a straight line (placed randomly or following some planned distribution).
[1] [2] This major is sometimes called agricultural and biological engineering, biological and environmental engineering, etc., in different universities, generally reflecting interests of local employment opportunities. Since biological engineering covers a wide spectrum, many departments now offer specialization options.
