Question

Which method of population forecast combines both arithmetical increase and geometrical increase method?

(a) Arithmetical increase method

(b) Geometrical increase method

(c) Incremental increase method

(d) Decreased rate of growth method

This question was addressed to me in quiz.

Asked question is from Population Forecasting topic in section Water Demand and Quantity of Environmental Engineering

Answer 1

The correct choice is (c) Incremental increase method

For explanation I would say: In the incremental increase method, the population for the next decade is found by adding to the present population, the average increase plus the average incremental increase per decade, hence combines both arithmetical and geometrical methods.
