Location Model Based on Population Distribution of Language

According to the analysis of population growth and immigration rules, a model based on Logistic population growth model is established to predicte the population of native speakers, the migrants and total language speakers of the 20 most languages in the next 50 years. According to the predictions, we conclude the future distribution of main languages of the world. Moreover, an evaluation system is built considering the geographical location and the power of every city. The system is helpful to decide where to open new international office in order to work effectively with the development trend of language spread.
