1. Introduction
Population is important to know because it gives us estimates on how many and how much of things we need. It is also important because we need to know how fast the world is growing. Studying population  helps officials to be sure that there is enough space for humans in the future. The number of people on the planet has doubled from 3.5 billion to seven billion in just a half century. While we’ve made great strides in educating people around the world about family planning and birth control, the global fertility rate still hovers around 2.5 children per woman. At that rate, population will grow to 11 billion by 2050 and nearly 27 billion by 2100. .

2. Population
A population is a summation of all the organisms of the same group or species, who live in the same geographical area, and have the capability of interbreeding simply a particular section, group, or type of people or animals living in an area or country. The human population is the total number of human beings on Earth.  United States Census Bureau (USCB) estimates that the world population exceeded 7 billion on March 12, 2012. According to a separate estimate by the United Nations Population Fund, it reached this milestone on October 31, 2011.

3. Population of Bangladesh
The population of Bangladesh is close to 150 million, making it the most densely populated country in the world, with the exception of several city-states. On a per sq km basis, it is three times more populated than Indian and seven times more populated than China. Nevertheless, what is not well known is that there are several other sizable areas in the world which are just crowded- Java (Indonesia’s principal island), for example, has a population density equal to Bangladesh’s.

From the table above and figure below it is observed that the total population in Bangladesh was last recorded at 142 million people in 2011 from 50.8 million in 1960, changing 200 percent during the last 50 years. Population in Bangladesh is reported by the World Bank. Historically, from 1960 until 2011, Bangladesh Population averaged 97.2 Million reaching an all time high of 142 Million in December of 2011 and a record low of 50.8 Million in December of 1960. The population of Bangladesh represents 2.18 percent of the world´s total population which arguably means that one person in every 46 people on the planet is a resident of Bangladesh.

4. Population Growth rate of Bangladesh
The average annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative. Population growth rate of Bangladesh is 1.37 % (Source: BBS, population census, 2011). In comparison with other countries around the region, this growth rate level places Bangladesh at an intermediate position between the group of low rate countries (Thailand, SriLanka, Myanmar) and the group of medium rate countries (India, Malaysia) Figure 2 : Population Growth Rate of Bangladesh since 1960

Bangladesh had high rates of population growth in the 1960s and 1970s. Since then however it has seen a marked reduction in its total fertility rate. Over a period of three decades it dropped from almost 7 to 1.34 in 2011 Table 2: Population Trend...
