ABSTRACT
Rural and urban developments are critically important in the future of almost every nation, and the complexities of these processes are enormous. Taxation, transportation, education, law enforcement, population growth, land tenure, and competition between cities and rural areas are among the many factors involved. The CITY GROWTH model addresses the causes of urban growth and decay, which in itself is a matter of national significance. The Urban Database Management System is a mapping and data management system for application to urban areas. The Housing Needs Assessment (HNA) model uses data describing a country’s housing stock, demographics, and family income to compute a twenty-year projection of the nation’s housing needs and the amount of capital the government will have to contribute to satisfy those needs. The HNA model projects housing needs by determining different components of total housing need and then combining them.
