crude death rate (CDR)

malthusian theory
Thomas Malthus believed that food production would increase steadily, but the same amount each generation. he also believed that people would not limit the number of children they had, so the population would increase exponentially. population would grow faster than food production, so widespread starvation would ensue if people would not voluntarily limit population growth
neo malthusians
people who have adapted his basic ideas to modern conditions
