Increase in population of a rapidly growing city, may be estimated by:

Several general methods are in common use  for making population projections for areas and communities  A variety of procedures and techniques has been developed under each of these general methods The general methods are:

• Graphical or mathematical projections of the curve of past population growth .
• Projections based on relationships of population growth in an area to that in other areas.
• Projections of net migration and of natural increase .
• Forecasts based on specific estimates of future employment and other occasionally used methods.

In  practice, few studies will use one method in the manner described in this report. Frequently, a particular area will have conditions which will best be met by adopting a unique method.

The most accurate answer is

2: geometrical method

I think you may use all options. Thank you.

Thanks En. Alex.

I will choose #3.

I agree with

3: incremental increase method

all of them are appropriate but geometrical method is more suitable.

Geometric method is the answer

as i knw i  have seen the estimations in graphical format, not sure abt the formula though

Option 4   :   graphical comparison method
