Population growth is a matter of note, if the population growth is not controlled, it
will be difficult for the government to make prosperity. In 2010, In the city of
Makassar was recorded 1,339,374 people with a growth rate of 1.65 percent every
year. This study aims to predict the number and rate of population growth in
Makassar city in 2017 by using Leslie Matrix. The factors which influence the
population growth are the fertilit rate, the survival rate, and the age range of the
population. The steps taken to predict the number of population p for the next year
with using Leslie Matrix are forming a vector column n (t) whose entry is the
initial number of population every age class. The second step is obtain the value
of n (t + p) which is the population number for the next year p than use the
formula n ( t + P) = A
p
n (t) with A is the Leslie Matrix. And the last step, specify
the dominant eigen value. The results obtained in 2017 predicted a total of
749,090 inhabitants with eigen values λ
1
=1.01 indicates that growth tends to raise.
