Show Tables 9 and 10 are more readily interpreted when converted to percentage form to show the male/ female composition of the labor force, as in Tables 11 and 12. In Tables 11 and 12 it may be seen that the use of the constant LFPR tends to bring about an increase of over one percent in the male composition of the Weber Valley labor force in the projections from 1975 to 1995. On the other hand, use of the dynamic ( U. S.) LFPR, tends to increase the female component of the labor force by slightly under one percent over ther period 1975- 1995. These differences are not earth- shaking, but are noticeable. We may conclude from the above, for reasons of practicality, the application of constant 1970 LFPR to the Wasatch Front group of counties ( as a regional unit) will not appreciably affect the total figures of population, labor force, or inmigration in any future year, but that the female composition of the labor force will be underestimated for the regional unit by proportions of up to nearly three percent by 1995. The Wasatch Front group of counties are nearly the same as the Weber Valley group, hence the generalization of the preceding sentence may be made fairly safely. However, since most of the jobs which employ women will be in Salt Lake County, we cannot be sure that the UPED model's underestimate of the female composition of the labor force in that County will not be significantly greater than three percent by 1995. The OBERS Projections for Utah and for the " Salt Lake Region" ( No. 151) The federally prepared OBERS projection of population, employment, and income have received wide publicity, but are essentially inapplicable when considered for Utah. The reason appears to be that data taken for a relatively small unit from a large modeling effort prepared at a national scale can reflect a number of distortions or anomalies. 21 |
