why do cities grow
- natural increase - birth rate higher than death rate, higher in LICs and NEEs because lots of young adults and improved health care
- rural-urban migration - push- farming is hard and poorly paid and usually subsistence so nothing to sell, rural areas isolated so fewer services, pull - higher standard of living, better medical facilities, better chance of education
