4⃣ Demography 1) Births Flashcards
What are the four factors which affect the decline or stable population growth
⚫️births and immigration
➡️increase the population
⚫️deaths and emigration
➡️decreases the population
⚫️natural change
➡️number of birth minus number of death
⚫️net migration
➡️number immigrating into a county minus the number emigrating from it
What is demography
⚫️study of the population
➡️including factors affecting
➡️size and growth
Describe the UKs population
⚫️grew from 37m in 1901
➡️to 61m today
➡️in 2031
➡️should reach 71m
⚫️growth mainly due to
➡️natural changes
➡️rather than net migration
What are the two measures of births
⚫️birth rate
⚫️total fertility rate
Describe the birth rate
⚫️number of live births per 1,000
➡️of the population per year

➡️by 2007 - fallen to under 11
⚫️but there has been fluctuations ➡️three baby booms ➡️after the two world wars ➡️and in 1960s ➡️the rate fell sharply in 1970s ➡️rose during 1980s and early 1990s ➡️and then fell ➡️until the recent increase in 2001
Describe the total fertility rate
⚫️average number of children
