Geography Study Materials and Hand-outs

Year back from now i was assigned  to read about South-east Asia and Its demographic characteristics by my course teacher. I tried to gather information through various search engines Of all the changes that swept Southeast Asia over the three decades since the formation of ASEAN, the transformation of population processes and trends have been among the most striking. Southeast Asia in 2002 had 8.6 % of the world’s population with 536 million people compared with 7.2% in 1950 (population Reference Bureau, 2002). The post-war period has seen the population of Southeast Asia increase almost three times. The period following the formation of ASEAN has seen the population of the region double from 253 million. The regions population growth rate peaked at 2.52 % annum in the late 1960s up from 1.92 % in the early 1950s and subsequently falling to 1.4 % in 2002 (UNESCAP). However, the changes in the size and growth of the population are only part of the story, and there have been dramatic

The dependency ratio is the proportion of the economically dependent part of the population to the productive part. The dependency ratio tells us how many young people (under 16) and older people (over 64) depend on people of working age (16 to 64). The dependency ratio is worked out with this formula Bangladesh has 33.60% of its population less than 15, and 4.80% over 65. This makes 61.6% (100 - (33.60+4.80)) between the ages of 15 and 64. It is really alarming and unfortunate that more than half of the people of Bangladesh are dependent to the economically active people. There is a hope and hope is that the large numbers who were born in the 1960s to the 1980s are now becoming economically active and as a result, the dependency ratio is falling.

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) Population Growth Rate of Bangladesh since 1960                                                                                 Data Source: World Bank  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.  From the table given below it is observed that the trend of avera

Population density of Bangladesh Population density is a measurement of the number of people in an area. It is an average number. Population density is calculated by dividing the number of people by area. Population density is usually shown as the number of people per square kilometer. Bangladesh has the highest population density among large countries, 1,237.51 persons per square kilometer, and 12th overall, when small countries and city-states are included (Source: CIA world Fact Book: 2012) Sustained population growth has pushed the population density from 290 to 1237 people per square kilometer between 1950 and 2012. Population tripled during this period from 42 million to 149 million. Bangladesh's high population density is prevalent across the nation except in the mountainous Hill Tracts in the Southeast, the Sundarbans mangrove forests in the Southwest, and to a lesser degree the Sylhet area in the Northeast corner. Due to huge population size, the density o
