In both the Transitional phase and the Industrial
phase the birth rate is greater than the death
rate so exponential growth is a occurring in both
of these phases.
However, in the Industrial Phase, the birth rate is
decreasing, so the RATE OF INCREASE is
decreasing (slowing down of growth rate).

The growth rate of 0.8 % (an increase of 0.8 people per
hundred) is equal to an increase in the population of 8
per 1000.
Since there is no net migration, the births (per 1000)
must be 8 more than the deaths (per 1000) for this
country. So if the death rate is 20 per 1000 the birth rate
is 28 per 1000.
