... of positive reproduction and p. is the mean of <j>(a) , then a close approximation to r is obtained with one iteration and an ad- justment based on the error in fit (Bar- .elay, 1958, pp. 220-222; Coale, 1957). The alternative approach is to solve for r in the polynomial r2 r 3 -In Ro + rp. - - ri + - ka = 0...

... in the United States. The ad- justment for each age-sex group involved the following steps: (a) An initial estimate of emigration was calculated using equation (l). (b) The resulting number of emigrants was "revived" to 1960 by dividing the initial estimate by the appro- priate survival rates. This hypo...

... for the last row, which contains only a one in the diagonal. (A special ad- justment must be made for births to the 7-up category.) Let us describe a single cohort and thus dispense with the superscript T. Within this cohort we will define all births as occurring to women of ages 14-49, inclu- sively...

SUMMARY AND CONCLUSION In this paper, we have presented an ad- justment-of-rates procedure which can be legitimately applied to cross-tables. The suggested method is based on the multipli- cative model and depends...

Before making the calculations, an ad- justment was made for IUD patients (11 per cent of the total) who became lost to follow-up (LFU). Analysis of a study of IUD patients in the Commonwealth...

... that the sex ratio of late fetal mortality (column 4) is not a realistic measure of the risk of such mortality for male and female products of conception. This is the case because sex ratio calculations do not provide ad- justment for the number of conceptuses of each sex at risk. Hence, sex ratios of late...

...- groups are identical or to have exact ad- justment factors for each subgroup under consideration. This latter possibility is not feasible-the appropriate adjustment fac- tors simply are not available for each sub- group of interest. For example, it is not possible to obtain information on the pro...

..., and the estimated January 1, 1960 figure was 920,469. The need for an ad- justment of approximately 7 percent in all single year of age color-sex groups to make the 25 percent sample of the returns correspond with the 100 percent count has already been stated. This "corrected" fig- ure is then uniformly reduced...

From the purely administrative ap- proach to the problem of family planning evaluation the concept of CYP may be meaningful and may be translated into births averted. Potter's...

.... The reasoning for this ad- justment is as folIows. The same number of moves would be counted regardless of whether the interval is six or twelve months. Hence, the numerators of the indexes are comparable. However, twice as many intervals are counted in the de- nomina tor when the intervals are six rather than...

... of migration, redistri- bution of population and economic ad- justment tend to be the more often mentioned concerns. Some serious work is reported to be in progress to understand the relationship between employment and in-migration (Greenwood, 1976, pp. 419-421). Also, Shaw (pp. 143-200) lists over a dozen...

...- justment in Eq. (1) can be extended to age-specific fertility rates: the ratio between the observed fertility rate at age a and at time t, and the hypothetical fertility rate that would have been observed if there had been no tempo effect, equals 1 r(a,t). The age- and period-specific tempo change r(a,t...

... that the intermediate quantities are of in- terest in themselves. The method applies increasingly available data, but, in the ab- sence of an "ideal" data set, certain ad- justments are necessary, and these are presented in the technical appendices fol- lowing the concluding discussion.

Consequently, the last five enumerations have yielded data on both core and peripheral segments of the homeless...

... or for a given area, a compen- satory adjustment should be introduced into future estimates. Figure 1 shows, however, that there is only a very weak correlation between the percentage errors of the 1950 and 1960 state estimates from Method II. Moreover, when no final ad- justment is made to a national control...

No special ad- justment of the data has been made for the possible double counting and/or un- dercounting arising from this difference of 11 months.

....) The important effects of age and mari- tal status at first birth on the pace of sub- sequent fertility clearly remain after ad- justment for these potentially confound- ing variables (Table 3). As we would expect, the adjustments alter the effects for "all" intervals somewhat more than for the "intended...

.... The constructed distribution would then be used as the beginning point for deriving values for a hypothetical cohort, the observed results from the second sur- vey providing the end point. Such an ad- justment might be useful in cases where the dates of the surveys do not quite give an exact five-year interval...
