Development often takes place in an uneven way. A country may have a very high GDP - derived, for example, from the exploitation of rich oil reserves - while segments of the population live in poverty and lack access to basic education, health and decent housing.
Hence the importance of human development indicators, measuring the non-economic aspects of a country's development.
Human development indicators include:
Life expectancy - the average age to which a person lives, eg this is 79 in the UK and 48 in Kenya.
Infant mortality rate - counts the number of babies, per 1000 live births, who die under the age of one. This is 5 in the UK and 61 in Kenya.
Poverty - indices count the percentage of people living below the poverty level, or on very small incomes (eg under £1 per day).
Access to basic services - the availability of services necessary for a healthy life, such as clean water and sanitation.
Access to healthcare - takes into account statistics such as how many doctors there are for every patient.
Risk of disease - calculates the percentage of people with diseases such as AIDS, malaria and tuberculosis.
Access to education - measures how many people attend primary school, secondary school and higher education.
Literacy rate - is the percentage of adults who can read and write. This is 99 per cent in the UK, 85 per cent in Kenya and 60 per cent in India.
Access to technology - includes statistics such as the percentage of people with access to phones, mobile phones, television and the internet.
Male/female equality - compares statistics such as the literacy rates and employment between the sexes.
Government spending priorities - compares health and education expenditure with military expenditure and paying off debts.
