What objections do neo-malthusians have with demographic transition model?

Answer 1

The DTM is used to classify countries into general groups. Hence, it is unable to take into account evolutionary changes in the process of population growth and classify diverse population into distinct but coherent stages of the development process.

Neo-Malthusians argue that the long-term fertility of a population depends on the most rapidly-breeding subgroups within the population. In the short term, the overall population growth rate may slow as most of the existing people have fewer children, but if a rapidly-breeding subgroup sustains its high fertility, it will eventually expand its numbers and restore the whole population to high fertility. This is similar to the evolution of resistance to pesticides in insects, and to antibiotics among pathogens: the first applications kill large numbers, but a few surviving resistant individuals may eventually make good on the losses through exponential growth. In other words, a criticism of the DTM is that it is only valid if the fertility-lowering social changes that caused the DTM in present-day industrial nations permanently lower the fertility of every subgroup within each nation. Garrett Hardin doubted that purely voluntary Birth Control could achieve that result; Hardin argued that voluntary birth control merely selects against the people who will use it
