Many urban sociologists focus behind the concept behind human overpopulation. Perry Burnett, who studied at the University of Southern Indiana, researched behind the idea of Urban sprawl and city optimization for human population. Some sociologists would criticize that urbanization could range issues from racial discrimination to high income taxes. Burnett would counter the idea that urban overpopulation could actually benefit the efficiency of cities. His work would equate optimal resources, incomes, households, etc. to display that larger and more city sizes would be more beneficial through more equal income and land distribution.
