Having low literacy skills could impact everything from reading a newspaper and balancing a checkbook to wise consumer decisions and job advancement. This study estimates adult literacy measures for Cuyahoga County, Ohio and its municipalities. It is also important to have a sense of how many children are at risk for developing literacy problems as adults, and these estimates are also generated. Finally, many efforts are already underway in communities across the county to try to help those who do struggle with literacy issues. The last portion of the research analyzes the distribution of literacy service providers. Appended are: (1) Difficulty Values of Selected Tasks Along the Prose, Document, and Quantitative Literacy Scales; (2) Reference Map for Cleveland Neighborhoods, Inner-Ring Suburbs, and Outer-Ring Suburbs; (3) Mean Literacy Proficiencies by Cleveland Neighborhood and Suburban Municipality, 1990 vs. 2000; (4) Percent at Level 1 Literacy by Cleveland Neighborhood and Suburban Municipality, 1990 vs. 2000; (5) Percent at Level 1 or Level 2 Literacy by Cleveland Neighborhood and Suburban Municipality, 1990 vs. 2000; (6) Census Variables Used to Update Reder's Mathematical Literacy Models; (7) Other Regional Literacy Measurements and Comparisons between Cleveland and Other Ohio Cities (Based on results from Jack Miller's Study); (8) Distribution of Births to Mothers Who Did Not Have a High School Degree, 1998-2002; (9) Percentage of 4th Graders and 9th Graders who Passed the Proficiency Tests; (10) Educational Attainment for the Civilian Youth Population Aged 16-19 by Suburban Municipality and Cleveland Neighborhood, 2000; and (11) Estimated Number of Adults and Children with Possible Literacy Problems.
