This 2018 Report on Child Care in Cook County examines the availability of child care to families in different parts of Cook County in FY2017, the year ending June 30, 2017. We present the various settings in which child care takes place, the number of children that can be served in each type of care, and the fees that parents pay to different types of providers. Challenges faced by families in relation to the cost of child care and state efforts to subsidize that care are also explored. Finally, we review policy options that could make child care more affordable and accessible to families throughout Cook County. (author abstract)
