Average number of children women will have during their fertile years has risen in recent years, but it is still much lower than in the past. 1.63 children per woman in 2001, rose to 1.83 by 2014. However, this is still far lower than the peak of 2.65 children per woman in 1964 during the 1960s baby boom.
The education of women is the most important reason for the long term fall in birth and fertility rates. Because women are choosing careers, to not have children, delay having children or having less children
Children are an economic liability & cost money. Laws banning child labour, changing norms & children at school longer. - cost of raising a child is increasing every year - £235,000 from birth to 18 and rising to£271,000 if going to 21 (uni).
Birth rate has decreased in the 20th century but increased slightly in the 21st due to immigration because immigrant families on average have more children, and cultural reasons e.g. not using contraception
Smaller families mean that women are more likely to be free to go out to work, creating the dual earner couple typical of many professional families
Falling fertility rates mean fewer children, so childhood may become lonelier experience as fewer children will have siblings and more childless adults may mean fewer voices speaking up in support of children's interests
Fewer schools and maternity and child health services may be needed, affects the cost of maternity and paternity leave and the types of housing that need to be built
Ageing population - One effect of women having fewer babies is that the average age of the population is rising. There are more old people relative to young people
