The study of population is required in planning so as to determine the size of human resources in a locality and ascertain their various needs and consider their interests and traits for the economic growth of the community at the local level. Human resources and their needs could be specifically identified by studying the population size, growth, structure, distribution, density, composition and changes due to births, deaths, inmigration, out-migration, transfer of groups in the same population such as marriages, separation, divorce and other socio-economic characteristics and the causes and consequences of those factors. Likewise, the age of the population determines the potential labor force and identifies the areas with considerable unemployment rates. These data guide the planners in redirecting development towards the concerned area and create job opportunities for existing and projected population.
Needless to say, the population size, its growth, spatial and age distribution affect the demand for economic goods and services such as food, clothing and other manufactured products, and the need to generate employment opportunities. An increasing population connotes an increasing demand for housing with necessary amenities. As consumers, the size and composition growth of population determine the demand for water and power supply for households, drainage system and other community utilities such as transportation.
While land resources are definite in the area and sometimes limited, or even subject to liquefaction, population density and rural expansion generally increase. Thus, population growth is a major controlling factor in the maintenance or degradation of ecological balance and the massive conversion of protection and production lands like agricultural and forestlands to urban uses.

Population projection is basic and very important in Land Use Planning. This is the means to enable the planner to forecast the size and growth of the population in a study area and direct the future utilization of available resources to meet the needs required by such size of population.
In planning, it was always wise and safe to project the needed parameters. Projections were made for the next ten (10) years 2003-2012 particularly for the total population, population by barangay, population by age group, school-going age, population density, and households population. Mathematical methods of projections, specifically Geometric and Linear Growth Approaches were used. Ratios and preparations were also resorted in some computations.
Population size and compositions were projected in order to provide planners an idea for the goods and services to be produced. The projections were sourced out from the results of the total population projections.
The population of Bani is expected to reach 56,006 by year 2012 representing an increase of 13,182 from its level of 2000. This means that the municipality has to prepare itself to accommodate a larger number of population in the future.
Urban population is expected to reach 6,297 by year 2012 representing an increase of 1,482 from its level of 2000. The rate of population growth is faster in the urban area than in the rural area, hence it is expected that urban lands shall be expected towards the fringes of Poblacion.
Taking a closer look at the projections by age-group, 13.24 percent of the highest increase shall be contributed by ages 5 to 9 at the peak of production group. Population growth rate becomes much faster if population management will not be taken seriously during the planning period.
