Research on China’s Population Trend Based on UN Population Data
This present paper is based on the annual worlds population data announced by the United Nations Population site. According to China’s population data in 1950-2005, we derive linear, hyperbolic, exponential, logarithmic and parabolic regression function respectively in the first model for both sexes population and male (female) population. Through comparative analysis of the data, we identify the most suitable regression function and predict the values of both sexes population in 2006-2030 in the 95 percent confidence level. In the second model, we divide long period into more detailed intervals. By virtue of the Mathematica software, we analyze the population data and then obtain the best fitting subsection regression function. Consequently, a more accurate prediction is achieved.
