| To test whether people with names associated with a specific religion were treated differently when applying for a house or flatshare, the Guardian sent almost 1,900 requests to properties listed in five locations – London, Aberdeen, Devon, Sunderland and Leicester – within a two-day period in the last week of October. | To test whether people with names associated with a specific religion were treated differently when applying for a house or flatshare, the Guardian sent almost 1,900 requests to properties listed in five locations – London, Aberdeen, Devon, Sunderland and Leicester – within a two-day period in the last week of October. |
| The wording of the two requests were different but similar in tone and length. To avoid any possibility of being rejected on a first-come-first-served basis, the requests were sent within a few minutes of one another and were alternated, meaning that in 50% of cases “David” made first contact and in 50% “Muhammad” did. | The wording of the two requests were different but similar in tone and length.

| The sample size was 948 ads in total. The responses were categorised into positive/neutral responses (those who opened a conversation and/or offered a viewing), negative responses (for example a message saying the room was gone) and no response (those who had not responded to the initial message within a week of the initial contact). A positive or neutral response was assigned a value of one and a negative or no response was assigned a value of zero. | The sample size was 948 ads in total.
