Let, 
be the initial population,
Given,
The population is decreasing by 3% each year,
Thus, the population after t years would be,
Since, if a population is changing by a constant rate then the population after t years is,
Where, r is the rate of changing per period.
Hence, in the given situation the population is changing by the constant rate.
