Projected Population Numbers and Rates

Low fertility rates may not translate to low birth and population growth rates given that the number of men and women in the production carder of a country is large. A larger sexually active population is often associated with large number of population. At this point in time, more fertile women tend to give birth to children. However, although the production per an individual is low the aggregate contribution of these birthrates to the general growth of the entire population is relatively high. The population growth rate associated with women producing nearly an equal number of children or fewer off springs is called demographic momentum (Geisel, Vilar and Rubi 2011). Demographic momentum is often significant in countries often developing that experienced rapid fertility rates in the 20^th century.  The reduced birth rates figures over the past two decades have relatively lowered the rates of population growth despite a continued decline of death rates. The ability to contain birth rates has relatively slowed the growth of population both developed and developing economies. Stable birth rates and relative increase of death rates courtesy of aging populations has naturally decreased the Germany and Italy populations relatively. Other emerging economies seeking to replicate the same are Japan and stain. These countries have a remarkable stability of birth rates and are experiencing an increase in its death rate figures. According to (Steele 2004), the past 30 years has witnessed a remarkable fall in global growth rate to 1.5 percent from two percent a year. Global policy makers assert that the trend is expected to continue despite absolute figures pointing at a different perspective. According to absolute figures, global population is growing at an alarming rate i.e. it is growing faster than it has ever been witnessed i.e. by an estimated 240,000 a day (Steele 2004). The aforementioned is happening relatively because of the large global population base. For example, in the year 1995, the earth was a home to 5.7 billion people, a figure that is almost double the 1970s global standing. According to demographic scholars, courtesy of the current population growth rates and the population base, the world will be a home to additional 2.5 billion people in the next 35 years. Developing economies and other emerging economies are observed to be the greatest contributors of these figures. In the short run, rapid increase in developing economies population figures will lower the per capita income of the general populace (Simon, et al. 2012).
