Designed to illustrate the extent of disadvantage found in the state of Alabama between 1950 and the early 1970's, this statistical source book presents data (of use to policymakers, researchers, and the general public) on the following demographic indicators: (1) Families Below Poverty Level; (2) Per Capita Income; (3) Youth Dependency Ratio; (4) Unemployment; (5) Farm Operator Level-of-Living Index; (6) Housing; (7) Health Index; and (8) Functional Illiteracy. Data taken from a number of well established secondary sources, including the County and City Data Book published by the United States Department of Commerce, are presented in four parts. The introductory section presents specific objectives; a digest explicating the eight indicators of disadvantage; and a brief discussion on the data sources. Part two comprises the summary and highlights of the findings, presenting a summary table that contains the ranking of each county with respect to the eight indicators and an average rank and rank ordering for the countries, as well as figures displaying geographic concentrations. Part two also presents the extent of population dependency as reflected in four dependency ratios. Part three presents a general profile of Alabama with mapped figures showing general demographic characteristics of counties by selected classes. Part four contains source tables which complement the brief narrative on disadvantage in Alabama. (JC)
