THE 1972 ECONOMIC CENSUSES

Early in 1972...we asked the business community's help in providing us with the basic information about its business activities during the year 1972. The facts were requested so that we, in turn, could provide YOU with the data from various economic areas! NOW - the results are in! They're being analyzed...fed to computers...and published for YOUR use....YOUR needs...YOUR advantage in keeping up with the latest trends in the business and industrial worlds.

There are hundreds of reports coming off the press as fast as figures are tabulated.

ESTIMATES OF THE POPULATION OF IDAHO COUNTIES

1973

AND METROPOLITAN AREAS: JULY 1, 1972 APARTMENT

This report presents population estimates for July 1, 1972 and provisional estimates for July 1, 1973, for counties and metropolitan areas prepared under the auspices of the Federal-State 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 on the basis of a test of methods against the 1970 census. For a more detailed description of the program and an analysis of the test results, see Current Population Reports, Series P-26, No. 21, "Federal-State Cooperative Program for Local Population Estimates: Test Results-- April 1, 1970," April 1973.

County estimates for July 1, 1971 and provisional estimates for July 1, 1972 were published earlier in Current Population Reports, Series P-26, No. 9. The provisional estimates in that report are superseded by the numbers published here.

The estimates shown here for the 44 counties in the State were prepared by the Division of Vital Statistics, Idaho State Department of Environmental Protection and Health. 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.

The estimates shown for July 1, 1972 are based on an average of the following methods,

adjusted to agree with the July 1, 1972 State
estimates published in Series P-25, No. 508.

1. The Regression (ratio-correlation) method.
In the Regression method a multiple regression
equation is used to relate changes in a number of
different data series to change in population
distribution. 1 The series of data used in the
Regression method for Idaho counties are: three-
year average of resident births (X1), three-
year average of resident deaths (X2), covered
employment (X3), and total school enrollment
in grades 1 through 12 (X4). The prediction
equation for Idaho for the 1970's is given by

A

Y = 0.0399 0.4045X1 +0.1738X2

+ 0.0868X3 + 0.2837X

2. Component Method II. This method employs vital statistics to measure natural increase and school enrollment to measure net migration. The estimates made by the Census Bureau's Component Method II are specific to the civilian population under 65. To this population is added an estimate of the resident military population based on station strength statistics and an estimate of the population 65 and over based on Medicare statistics.'

'Descriptions of methodologies are given in Current Population Reports, Series P-25, No. 427 and 460. Modifications made to the methodologies for the current series will be given in forthcoming reports in Series P-25.
