I live in York. A place – the Heritage Index tells me – low for assets and high for activities and which comes 97 of 325 English local authorities in the league table, only just in the top third. My first reaction on reading this was to be a bit offended. Heritage seems to have become a kind of competition and we don’t seem to be wining. My more measured reaction was to have expected York’s rankings in each category – assets and activities – to be the other way round. My next step was to download the data and its sources. Here I can see York, its buildings, histories, people and local politics that I’m part of, and embroiled in, set out in categories and numbers.
