How much research did you (and others) do before choosing your village?
Lots. Key things were basic services (shop, post office, GP in next village) and reasonably regular public transport link to nearest city as I didn't drive we'd moved from London and never had a car and community activities such as baby groups, book groups, general social activities (I was on maternity leave), a decent school, things going on for children.
Unfortunately, it's more difficult to research 'How racist/xenophobic are your fellow-villagers?' or 'How often will I be subjected to slurs to do with my country of origin and accent?' without actually going to live there for long enough for people to become unbuttoned around you, especially as we are very close to a hugely ethnically-diverse city.
Or 'Are working mothers so rare in the village and environs that childcare simply does not take account of FT jobs and it's considered anomalous by other parents in your child's class at school, who remark on it a lot in tones of incomprehension?'
Or 'Is the nice current vicar about to depart and be replaced by an evangelical loon who rocks up at school assemblies and tells your child the Book of Genesis is literally true ('because it's in the Bible'), and that celebrating Hallowe'en is 'sinful' and 'unChristian'?
Or 'Because the local district council has failed to have a five-year-supply of housing, will it suddenly wave through housing developments which have been consistently refused for years on the grounds of of overwhelming road access and services, thereby tripling the size of the village within two years?'
The one thing I simply did not know to check in advance is 'underlying soil conditions' -- here it is dense clay which makes the very pleasant fieldpaths around the village through cultivated fields virtually impassable for months at a time, because you end up with a stone or two of clay attached to each boot.
