More than 200,000 people or one per cent of Ghana's adult population regard themselves as gay or lesbian, according a study.

The data has been collected by the Ghana Household Survey (GHS).

The 100,000 individual respondents to the survey provided the biggest pool of Ghana social data after the national census, the statistics service said.

95 per cent of adults identify themselves as heterosexual/straight while just one percent of adults see themselves as gay or lesbian.

Another 0.5 per cent of adults said they are bisexual and a similar proportion described their sexuality as 'other'.

Just under 3 per cent of adults responded "don't know" or refused to answer the question. Fewer than one percent of respondents provided no response.

The highest proportion of adults who identified as gay, lesbian or bisexual were in Accra, Takoradi and Kumasi with the lowest found in Tamale.
