  1. I download Land Registry price-paid data every month to monitor prices. The files I download are the yearly ones from 2005 onwards. My expectation was that the data for years in the distant past would be unchanging from one download to the next. However, that is not the case; even for the earliest years, there is variation. Attached is a plot that shows, for each year, the number of datapoints in the file (y axis) against the download date (x axis). E.g., for 2005 data, there are around 1000 fewer datapoints in the most recently downloaded data, compared to data download in Jan 2017. This is out of a total of approx 1 million datapoints. So in relative terms, the variation is not large. Nevertheless, it is surprising. There's also a common pattern in years 2005-2013. The number of datapoints consistently increased with each download until late 2017/early 2018, when suddenly there were large removals of data (the exact month of the removals varies). This raises a couple of questions: 1. Why were properties being consistently added to datasets from almost 15 years ago even recently? 2. Why was data removed in late 2017/early 2018? If anyone knows what might be going on here I'd be quite interested!
  2. Anna Powell Smith, a developer/data scientist, has created a plot of house prices per square metre, by combining Land Registry data with area data from Energy Performance of Buildings Data, see here: https://houseprices.anna.ps/ I think the Energy Performance data has only recently been made available, though I'm not 100% sure about that. It is at the following link, but you need to register: https://epc.opendatacommunities.org/ It should be possible to use the same idea to produce more accurate plots of price changes over time than is possible with the LR data alone.
  3. Article http://www.citylab.com/politics/2015/06/incredibly-detailed-map-europes-population-shifts/396497/ Dark BLUE patches show an average annual population FALL of 2 percent or more, the medium blue patches a fall of between 1 and 2 percent, and the lightest blue patches a fall of up to 1 percent. Areas in beige have experienced no statistically significant change, while the red areas show population growth. Municipalities in deep RED have experienced an average annual population RISE of 2 percent or more, the medium red of between 1 and 2 percent, and the pale pink areas of up to 1 percent. Hi-Res copy of the Map (8 MB) http://www.bbsr.bund.de/BBSR/DE/Home/Topthemen/Downloads/bevoelkerungsentwicklung.html If you study this theres a lot of trends you can spot: in most of Europe a move towards the coast. in the UK a move away from coastal areas. In most of europe a concentration of people moving near to big cities - but not right in the centre (probably due to prices) In the UK a concentration of people moving to big cities - mostly very central London. (probably due to our crap transport system) I'm not sure what this tells us about house prices - most new immigrants will be renting.
