[Recent data on the demographic problem of Bangladesh].

With a 1980 population of 90.6 million, Bangladesh is "one of the most densely peopled states. 91% of the population live in rural areas and 80% of them are agriculturally employed. As a food deficit country, this amounts to overpopulation, which makes Bangladesh very vulnerable to natural disasters. Growing at 2.6% per annum there are few signs of demographic transition as birth rates remain higher than in India. Projections cannot but reflect a crisis point in the near future."

A simplified model of spatiotemporal population dynamics.

This paper is an extension of the model of population growth and migration originally developed by H. Hotelling in 1921. This model consists of two ingredients, a logistic growth function and a linear spatial diffusion term. The author notes that the saturation population can be affected by the development of new technology and that improvements in transportation have increased the possibilities for migration. "Basic nonlinearities are introduced by use of a production technology with increasing-decreasing returns to scale. It is demonstrated how industrial takeoffs, population transitions, and agglomerative spatial patterns can emerge by changing the model parameters."
