Abstract
Objective: An administrative rezoning occurred in Taiwan in 2010. As a result, three city county duals were consolidated into three new cities: Taichung City, Tainan City, and Kaohsiung City. This study aims to investigate whether the consolidation would reduce the city-county mortality gap. Methods: Data on city/county mortality in total population, children aged 0-4 years, and adults aged 65 years and over, were obtained from Ministry of Health and Welfare. In addition to crude mortality rates, we also calculated age-standardized mortality rates. The Hodrick–Prescott filter was further used to separate long-term trends from time series data. The multiple regression was applied to examine the consolidation effect on mortality rate difference. Results: After the consolidation, the differences in both crude and age-standardized mortality rate between original city and original county have increased for total population and adults aged 65 years and over, but only the effect on the difference in crude mortality rate for adults aged 65 years and over was statistically significant (β=142.2, p=0.000). The difference in mortality rate for children aged 0-4 years has slightly declined after the consolidation, which was not statistically significant. Conclusions: There was no evidence that the consolidations had affected the mortality gap between original city and original county.
