Office of Education annual reports have yielded this statistical description of preprimary enrollment trends and changes during the period from 1964 to 1968. This report contains four pages of text, summarizing in prose form the significant trends and enrollment patterns and citing the source and reliability of the data. Information described and graphed includes total preprimary enrollment of 3-5 year olds; cumulative percentage increase of preprimary enrollment of 3-5 year olds; and analysis by age, color, region, family income, occupation of head of household, and place of residence. The most striking trend is the yearly rise in the number of 3-5 year olds enrolled even though there was a yearly decline in the population of this age group. In 1968, 33% of this population was enrolled. The report concludes with four extensive tables of data. (MH)
