The analyses in this presentation book, prepared by the Policy Research Division of the Office of Planning, Research, and Evaluation, Office of Economic Opportunity, reflect poverty statistics based on data from the Current Population Survey of the Bureau of the Census. These statistics reflect incomes of families and individuals which fall below specified income levels or poverty lines. These lines are adjusted to take account of such factors as family size, sex and age of the family head, number of children, and farm-nonfarm residence. Each year all poverty lines are adjusted by the Consumer Price Index so as to reflect changes in the cost of living. The poverty information contained in this book is presented in 28 tables and accompanying charts which are subdivided under the following headings: (1) Who are the Poor? (2) Some Selected Characteristics of the Poor; (3) Frequently Mentioned Poverty Groups; (4) The Increase in the Poverty Population between 1969 and 1970; and (5) Trends in the Poverty Population Over the Past Decade.
