    Adjustment For Area Comparability Of Statistics On Family Income From The 1960 And 1950 Censuses Of Population: Major Cities And Their Standard Metropolitan Statistical Areas
    (1962-12-01) Miller, Ann Ratner; Varon, Benison
    This is the third in a series of reports dealing with adjustments of census data to take account of changes in the geographic boundaries of certain large urban areas between the 1950 and 1960 censuses of population. The first two reportsl presented summarizations of unpublished tabulations from the 1960 Census showing some basic demographic characteristics of the populations living in areas annexed to large cities during the previous decade. The comparable data for cities in the present report differ from those in the earlier reports in that they are estimates rather than the results of direct census enumeration. This report also differs from the earlier ones in presenting adjusted data for Standard Metropolitan Statistical Areas2 and, as a residual, for rings surrounding the large central cities. The statistics for SMSA's are not estimates, however, but merely rearrangements of published census figures for 1950 to comply with changes in the counties included in specific SMSA's between the two censuses.

    Net Intercensal Migration To Large Urban Areas Of The United States 1930-1940, 1940-1950, 1950-1960
    (1964-05-01) Miller, Ann Ratner; Varon, Benison
    The present report includes data for the 51 cities in the United States with populations of 250,000 or more in 1960, their 48 Standard Metropolitan Statistical Areas,l and the two Standard Consolidated Areas of New York-Northeastern New Jersey and Chicago- Northwestern Indiana. The analytical summary which follows, however, discusses the data for 45 Areas only; excluded are the Honolulu SMSA, for which historical data are not available in the detail needed, and the four SMSAs included in the SCAs mentioned above.

    Historical Estimates of World Population: An Evaluation
    (1974) Durand, John D.
    A myopic view of history and underdevelopment of theory have been two shortcomings of demography, related to the pragmatism of the discipline and to demographers' predilection for precise measures. A healthy counterpoise is the current surge of interest in demographic history, where questions remote from current practical concerns invite study and exact data are scarce. Historical demography, hitherto an esoteric field of specialization, is now a robustly growing sub-discipline. Historians, archaeologists, and others are also joining in the exploration of neglected demographic fields of history. Demographer's horizons are being stretched, new frontiers of interdisciplinary contact are being opened, and the historical foundations of theory are being strengthened and extended.

    Population In 1960 Of Areas Annexed To Large Cities Of The United States Between 1950 And 1960 By Age, Sex, And Color
    (1961-11-01) Miller, Ann Ratner; Varon, Benison
    These tables were prepared in conjunction with a study of the growth of large cities and their surrounding areas being conducted by the Population Studies Center of the University of Pennsylvania. A major emphasis of the study will be the role played by migration in effecting changes in population composition and, to this end, we are interested in securing estimates of numbers of migrants by age, sex, and color. We plan to use· several measures of migration, among them that of net intercensal migration as indicated by the Census Survival Ratio method.

    The Estimation Of Intercensal Migration From Birth-Residence Statistics: A Study Of Data For The United States, 1950 And 1960
    (1968-02-01) Eldridge, Hope T.; Kim, Yun
    One of the principal objections to the use of census survival ratios for estimating net migration is the error that must arise from geographic variations in enumeration error and in mortality rates around the national averages. The possibility of reducing this type of error emerged with the tabulation, in two successive censuses, of birth-residence statistics for the native population of the United States by age, sex and color. By treating each group of persons having a common area of birth as a closed population, one can derive census survival ratios for the decade 1950-1960 that are specific for area of birth as well as for age, sex and color.

    Net Intercensal Migration For States And Geographic Divisions Of The United States, 1950-1960: Methodological And Substantive Aspects
    (1965-05-01) Eldridge, Hope T.
    The main purpose of this report is to carry forward the major migration series analyzed in Population Redistribution and Economic Growth, and to summarize developments in 1950-1960. In the process, considerable emphasis is placed upon comparisons between 1950-1960 and 1940-1950. Because the historica1 data exclude Hawaii and Alaska, much of the discussion deals with conterminous United States rather than with the total United States as now constituted. In addition, estimates derived by other methods are compared with those based on census survival ratios, and some attempt is made to evaluate the merits of each and to integrate the findings.

    Interrelations Between Industrial And Occupational Changes In Manpower United States, 1950-1960
    (1966-06-01) Gnanasekaran, K. S.
    One of the striking features of industrialization has been the great increase in the variety of jobs that accompany it, and the changing composition of these occupations in the course of further development. The factors responsible for such variations in occupational structure, their direction and magnitude need systematic investigation with a view to aid manpower planning. Under the circumstances of rising shortage of certain critical occupations in almost all countries, the study of occupational dynamics has come to the forefront in recent years. Further, high rates of employment in occupations that are either declining or not growing fast enough has underscored the need for knowledge about occupational trends in manpower so as to formulate effective full employment targets. Closely related to the task of ensuring balanced supply of different categories of manpower and avoidance of unemployment, is the educational and vocational training of people which perforce depends mainly on prospective occupational changes in the economy. Interest, therefore, of the educational planners in the present and future occupational trends has given an added impetus and urgency to occupational analyses and forecasts.

    Population In 1960 Of Areas Annexed To Large Cities Of The United States Between 1950 And 1960 By Household Relationship And Marital Status
    (1962-08-01) Miller, Ann Ratner; Varon, Benison
    This report presents the results of additional summarizations of unpublished materials from the 1960 Census of Population on characteristics of populations in areas annexed to large cities between the 1950 and 1960 1 censuses. An earlier report described the problem necessitating these tabulations and showed the data on age by color and sex. Here we are presenting the statistics on household relationship by color (Table 1) and on marital status for the population 14 years of age and over by color and sex (Table 2). We have, therefore, now summarized, for annexed areas, four of the five population items available for enumeration districts from the 1960 Census of Population. We do not at present have any plans to summarize the figures for the fifth item, which is the population under 21 years of age by single years of age.

    Methods For Analyzing Components Of Change In Size And Structure Of The Labor Force With Application To Puerto Rico, 1950-60
    (1969-09-01) Durand, John D.; Holden, Karen C.
    The increase or decrease of a country's labor force during a given period of time can be factored into the following components: A. Loss by death of labor force members. B. Net gain or loss by immigration and emigration of labor force members. C. Gain by entry into the labor force of individuals from the economically inactive population. D. Loss by retirement from the labor force into economically inactive status (including involuntary withdrawal on account of disability or for other reasons, as well as voluntary retirement). Likewise the change in number of workers attached to a given occupation or industry group of the labor force can be factored into the same four components, plus the fifth component: E. Net gain or loss by occupational or industrial mobility, i. e. transfers of labor force members from one occupation or industry to another. It is useful to subdivide components C and D as follows: C1 and D1. Labor force entries and retirements which would correspond to the maintenance of unchanging age-specific rates of entry and retirement (in the labor force as a whole and in given occupation or industry categories). C2 and D2. Entries and retirements due to changes during the period in the age-specific entry and retirement rates. The sum of components A, C1, and D1 can be considered as a measure of "natural increase" in the labor force as a whole or a given occupation or industry. This is the increase which would result from natural increase of the population and associated changes in its age structure without migration and without occupational or industrial mobility. Components B, C2, D2 and E are media through which the natural increase is modified under the influence of supply and demand factors.
