In population forecasting, the arithmetic increase method assumes that:
Percentage increase per decade is constant
Increase per decade is constant
Growth rate decreases uniformly
Growth follows a logistic curve
Compared to the geometric increase method, the arithmetic increase method generally gives:
Higher population value
Lower population value
Equal population value
Unpredictable results
Growth of population can be most conveniently represented by:
Straight line curve
Arithmetic curve
Semi-logarithmic curve
Logistic curve
The most suitable method for forecasting population of a young and rapidly developing city is:
Arithmetic increase method
Geometric increase method
Decreasing growth rate method
Graphical comparison method
Uniform increase method of population forecasting refers to:
Arithmetic increase method
Geometric increase method
Incremental increase method
Graphical extension method
Assertion (A): Geometric increase method assumes constant percentage growth. Reason (R): Population increases by a fixed number every decade.
Both A and R are true and R explains A
Both A and R are true but R does not explain A
A is true but R is false
A is false but R is true
The three basic factors responsible for population change are birth, death, and (a) .
The formula used in arithmetic increase method is Pn = P0 + (a) .
In geometric increase method, population is assumed to increase at a constant (a) rate.
When increase from decade to decade is assumed constant, the method used is (a) increase method.
Incremental increase method considers both average increase and (a) .
Graphical extension method is suitable when (a) duration extension is needed.
The population of a town in 1981, 1991, 2001 were 20,000; 22,000; and 25,000 respectively. Estimate the population in 2011 using arithmetic increase method.
(a)
A city had populations of 40,000 (1970), 46,000 (1980), 53,000 (1990), and 58,000 (2000). Find the predicted population in 2010 by arithmetic progression method.
(a)
Population in three consecutive years is 5,000; 7,000; and 8,400. Estimate the population in the fourth year using geometric increase method.
(a)
