Prevalence of Children with Special Health Care Needs in Metropolitan and Micropolitan Statistical Areas in the United States

Objectives We estimate the prevalence of children with special health care needs (CSHCN) in 70 metropolitan and four micropolitan statistical areas across the United States. Methods The data are from the 2001 National Survey of CSHCN, which was sponsored by the Maternal and Child Health Bureau and conducted by the National Center for Health Statistics. Prevalence estimates were generated for 74 metropolitan and micropolitan statistical areas (M/MSAs) and 45 individual counties that were represented by at least 1,000 children in the sample. To generate the estimates, the child-level sample weights (representative at the national and state level) were recalibrated within each M/MSA and county to match Census 2000 counts of the child population by age, sex, and Hispanic ethnicity. Results M/MSA-level and county-level prevalence of CSHCN are compared with national- and state-level prevalence, and within M/MSAs and counties, prevalence is reported by age, sex and race/ethnicity. Most, but not all, M/MSA- or county-level prevalence estimates did not differ significantly from state-level estimates. Some M/MSAs and counties that did not differ from their states in overall prevalence of CSHCN did show some differences in prevalence for certain demographic subgroups. Conclusions Metropolitan health departments and Maternal and Child Health agencies that serve urban areas may find these new small area estimates useful for program planning purposes. This study demonstrates the importance of assessing whether state estimates may approximate local area estimates of the prevalence of CSHCN.
