  • Population Changes in MEDCs. In most MEDCs population growth is stable. MEDCs have low birth and death rates. In some Germany the birth rate is actually lower than the death rate. This means there is a decrease in population or a natural increase of -0.1%. The major problem for many MEDCs is an ageing population.
  • There are 4 main variables which affect the population growth to either rise or decline according to the Population Balancing Equation. They are: B = Number of Births between the previous period (P1) and the current period (P2) D = Number of Deaths between the previous period (P1) and the current period (P2) Im = Number of people who migrate IN to the population.

  • Population growth is a common example of exponential growth. Consider a population of bacteria, for instance. It seems plausible that the rate of population growth would be proportional to the size of the population. After all, the more bacteria there are to reproduce, the faster the population grows.

Introduction. Population growth can be modeled by an exponential equation. Namely, it is given by the formula [latex]P(r, t, f)=P_i(1+r)^\frac{t}{f}[/latex] where [latex]P{_i}[/latex] represents the initial population, r is the rate of population growth (expressed as a decimal), t is elapsed time, and f is the period over which time population grows by a rate of r. A mathematical model of human population growth was introduced by an English economist named Thomas Malthus in 1798. The main assumption is that the rate of growth of the population is proportional to the current population. Mathematically, dP dt ∝ P ⇒ dP dt = kP This model actually pretty accurately reflected the population growth of the ...
