2 The Survey It is important to be clear about what the survey can, and cannot, achieve.
The survey cannot provide statistically reliable results. That requires a survey based on a large random sample of the population. Because so many LGB people conceal their sexual orientation, obtaining a random sample is not practical within the limited resources available to projects.
This means that the questionnaire survey will not give reliable statistical information about the extent of discrimination in a particular country.
But it will provide information about the experiences of the particular group of people who answered the questionnaire, and this allows a broad picture to emerge. Past experience in many countries shows that this information is quite sufficient to demonstrate that sexual orientation discrimination is a serious human rights issue requiring urgent action by government.
