Making sense of frequency data from third-party sources is difficult because they tend to use different time frames or cover different areas. For example - the Spatial Literacy In Teaching site covers Great Britain whilst the Taliesin-Arlein Names site covers England, Wales and the Isle of Man. Further work will take place to look at the data for other geographic areas and to obtain data for a wider selection of dates.
The data obtained to date is in two parts:
- Great Britain: gives an overview of the data for Great Britain as a whole
- York: Gives the data obtained for the City of York (Yorkshire, England)
