The United Nations report, National Human Development Report 2013, reveals that one in three people in Costa Rica recognize having a gay or lesbian family member, while six in ten claim to have friends who are sexually diverse.
The report released on Thursday did no ask for sexual orientation because of existing social censure may have inhibited responses.
The report also indicates that 34% of the people in Costa Rica agree with open expressions of affection, such as kissing or hugging in public between people of the same sex.
The percentage grew when asked about same sex couples being legally bound (as in marriage), with 39% in favour.
