Determine the expected population for a rural community of 1,500 people after 15 years if the community is losing population at a rate of 1%/y because of migration to urban areas. The birth rate is 20 per thousand per year and the death rate is 0.5 percent per year?

A water treatment plant in a city is to be upgraded to meet the needs of the population in the year 2025, and the water distribution system is to be expanded to meet the needs of the population in the year 2045 or 2055. The 2010-population of the city was 225000, and based on a saturation population of 2,500,000, the 2070-population is estimated to be 420000. Estimate, using decreasing rate of increase method, the city's population in 2025, 2045 and 2055 to facilitate the design of these systems. Don't attempt wrong

According to the City of Mankato, the population was 28,651 in 1980 and 39,309 in 2010. Estimate the population in 2070 using (a) arithmetic growth projection, (b) geometric growth projection, and (c) declining growth projection. Assume a saturation population of 100,000.
