As part of the BBC's Future Family week, exploring the nature of family life and the pressures it faces, we publish here five photo journals from around the world.
Alejandro and Teodora Iriondo are smallholders in the sub-tropical Yungas region of Bolivia.
Unlike Alejandro, who finished school at nine, their children are studying.
But healthcare, which Teodora needs, is hard to afford.
Sherifa Abdel Salam, a 30-year-old science teacher, lives with her husband and three daughters in a village in north-eastern Egypt.
At first she was sad to have borne no sons, but is now reconciled to what she regards as God's will. She also loves her daughters.
Sherifa used to argue with her husband but says she has learned to compromise, to avoid friction.
Philippe Stubbe rears a herd of 300 cattle with only his son to help him.
He gets little time off. His wife, Marianne, has a job which keeps her away from the farm during the day, and the family only eats together once or twice a week.
Philippe would like his children to take over the farm, but says they will need an extra source of income in order to prosper.
Shabnarayan Jhanjharia, aged 72, heads a family of 12, all except one of whom work on the family's four-acre farm in the Indian state of Haryana.
Two-thirds of India's one-billion-plus population are farmers, but Jhanjharia's grand-children may choose other careers.
The Haryana state government also wants to buy the family's land, to build a factory.
Bani works as a driver in the Indonesian capital, Jakarta, to support his wife and three children.
He is obliged to spend long hours away from home, to make ends meet. He had more contact with his father, when he was young, than he now has with his children.
His two boys, aged 10 and 14, appear to be model children, but both parents worry that family life is now less disciplined.
SIERRA LEONEAN FAMILY
Sierra Leonean footballer Abdul Karim Conteh has a happy, healthy family with four children aged two to 16.
His son hopes to follow his in his father's footsteps, his two eldest daughters are studying hard - albeit sometimes by candlelight, given Freetown's precarious electricity supply.
They eat together every evening - food is their single largest expense - except when Abdul Karim is working abroad.
