The Application of Markov Chain into the Forecast for Population Age Structure in Shanghai

By using the data of Shanghai's population age structure in 2004 2007, based on the forecasting model of Markov chain, the paper calculated the transition probability of the changes for population age structure in Shanghai. In the last, using the transition probability matrix predicted population age structure of Shanghai in the future. The conclusion is that: Aging trend is growing now and the next 10 years in Shanghai.
