Abstract:

This paper compares recent vital statistic variables from 88 Ohio counties. The variables are (1) Live Birth rate per 1,000 population, (2) Low Birth Weight rate per 1,000 live births, (3) Births to Unwed Mothers per 1,000 live births, (4) Teen Birth rate per 1,000 female population aged 10-19, (5) Total Death rate per 1,000 population, (6) Infant Death rates per 1,000 live births, (7) Neonatal Death rate per 1,000 Live Births, (8) Marriage rate per 1,000 population, (9) Divorce rate per 1,000 population, (10) Income per Capita, (11) Population Density, and (12) Abortion rate per 1,000 live births. Univariate analysis will look for outliers and check for the marginal normality of the variables. Mahalanobis distance may also identify outliers. A correlation matrix and matrix scatter plots discern relationships between the variables. Correlation of abortion rates with other variables is of interest. Principal component analysis determines dimensionality and identifies outliers. Cluster analysis investigates similarities between the counties and the appearance of outliers. Identifying outliers provides county, state and federal governments with insights to county needs.
