From the Sayoni website:
This survey is intended to collect essential information about queer, lesbian, bisexual and transgender women living in Singapore. Women of all ages, races and nationalities are welcome to take this survey, as long as your permanent residence is Singapore.
We encourage you to take this survey even if you have taken it in previous years. The collective results of this survey will be used for research purposes only, and will in no way be traced back to the individual user. We thank you for the great service you are doing for the community, in spending time to do this.
It should take approximately five minutes to do this survey.
This survey is brought to you by Sayoni.
