• 2.9 million is the population of the city in 1990 and 0.08 million is the increase per year in the population.

• 2.9 million is the population of the city in 1991 and 2.98 million is the population in 1992.

• 2.9 million is the population of the city in 1990 and 0.08 million is the decrease per year in the population.

• 0.08 million is the population of the city in 1990 and 2.9 million is the increase per year in the population.
