PARTMENT OF OMMERCE UBLICATION es P-26, No. 25 May 1973 ESTIMATES OF THE POPULATION OF NEBRASKA COUNTIES This series of reports presents population estimates prepared under the auspices of the FederalState Cooperative Program for Local Population Estimates. The objective of this program is the development and publication of State-prepared estimates of the population of counties using uniform procedures largely standardized for data input and methodology. The methods used have been mutually agreed upon by the individual States and the Bureau of the Census and were selected on the basis of the results of an extensive test of methods against the 1970 census conducted in late 1971 and early 1972.1 The estimates for July 1, 1971, and the provisional estimates for July 1, 1972, shown here for Nebraska counties were prepared by the Bureau of Business Research of the University of Nebraska. This agency was designated by the Governor to work with the Bureau of the Census in implementing and carrying out the Federal-State Cooperative Program. 1 For a more detailed description of the program, see Meyer Zitter, "Federal-State Cooperative Program for Local Population Estimates, The Registrar and Statistician, U.S. Department of Health, Education, and Welfare, January 1968, and "Federal-State Cooperative Program for Local Population Estimates: Status Report, January 1971, " The Registrar and Statistician, U.S. Department of Health, Education, and Welfare, April 1971. For a detailed analysis of the test results, see Current Population Reports, Series P-26, No. 21, "FederalState Cooperative Program for Local Population Estimates: Test Results--April 1, 1970." The estimates shown for July 1, 1971, and the provisional estimates for July 1, 1972, are based on an average of the following methods: 1. The Regression method is an estimating technique in which a multiple regression equation is used to relate changes in a number of different data series to change in population distribution.2 The series of data used in the Regression method for Nebraska are drivers' licenses (X,), school census (X2), school enrollment (X3), food tax credits (X), and Social Security beneficiaries (X5). The prediction equation for Nebraska for the 1970's is given by ŷ = 0.30X + 0.10x2 +0.10x + 0.40X4 + 0.10x5 2. The Census Bureau's Component Method II is an estimating technique which employs vital statistics to measure natural increase and school enrollment as a basis for measuring net migration. The estimates made by the Census Bureau's Component Method II are specific to the civilian population under 65, with Medicare statistics used to estimate the resident population ages 65 and over. The total resident population is derived by adding estimates of the military station strength in each county to the estimates of the civilian resident population. 2The Regression method used in making estimates of Nebraska counties differs slightly from that used in other States.

Corresponding estimates for other States in the program will be published as they become available. The jointly prepared estimates for counties shown here are presented by the Bureau of the Census in lieu of preparing competing estimates. These estimates for counties are consistent with independent State population totals regularly prepared by the Bureau of the Census and published in the P-25 series of reports. County populations for 1970 reflect corrections in the census count made since tabulations of the census. Counties with corrections of more than 500 are Sarpy and Webster. The official 1970 resident State total shown on the table may differ slightly from the sum of the counties because of corrections made subsequent to the release of the State figure. The estimates presented in the table have been rounded to the nearest hundred without being adjusted to the State total, which was independently rounded to the nearest thousand. Percentages are based on unrounded numbers.
