Map of respondents’ geographical distribution at a 10 km × 10 km square scale. Location was derived by calculating coordinates from their postcode prefix by using a Google Maps API Key retrieved in 2019 (Google 2019), converting them to Easting and Northings and mapping them on to a base BNG layer from the public repository on www.naturalearthdata.com. Darker purple squares indicate 10 km × 10 km grid squares with > 1 respondents. Note that the Channel Islands and Shetland Islands (which contained two respondents each) are omitted due to space constraints b RNP distribution in the UK at a 10 km × 10 km square scale, from the NBN Atlas Partnership (2021).
