That's a difficult question to answer without giving a lot of detail.
Traditionally you see more older people living in the country (or by the sea) and that hasn't changed a massive amount, those are still the places people like to retire to. But you also see younger people moving into villages with the help of housing schemes and affordable accommodation, so the average age has come down. You see more people interested in this way of living in the country, who have had enough of the city slog, start up businesses farming more exotic crops, animals and products, even British wine has done really well in recent years. With more people working from home you will see these things become more diverse and competitive over time. Also fairly large immigration from eastern Europe has happened to certain smaller towns and villages, but this will decrease now the UK has left the EU.
The numbers of people living in urbans areas has steadily increased over the past 50 years and I doubt that will change if you think how quickly urbanisation happens. At the moment it's around 11 or 12%.
