Teenage parenthood is recognised as a significant disadvantage in western industrialised nations. It has been found to increase the likelihood of poverty and to reinforce inequalities. This book explores, for the first time, the links between welfare state provision and teenage reproductive behaviour across a range of countries with differing welfare regimes.Drawing on both welfare state and feminist literature, as well as on new empirical evidence, the book compares public policy responses to teenage parenthood in each 'family' of welfare regime: Nordic, Liberal and Continental (Western European); analyses the different socio-political contexts in which teenage pregnancy is constructed as a social problem and identifies best practice in Europe and the USA.Countries included in the study are the UK, USA, New Zealand, France, Italy, Poland, Denmark, Norway, the Canadian province of Quebec and Russia. The contributors are all internationally recognised experts in the fields of welfare and/or gender studies."When children become parents" is important reading for a wide audience of students, policy makers, practitioners and academics in sociology, social policy, social geography, education, psychology, and youth and gender studies.
