Blackthorn is roughly rectangular shaped. It is based around 4 roads - Station Road, Lower Road, Thame Road and Weir Lane.
Blackthorn once had (at various times) two public houses (The Rose & Crown, The Royal Oak), a butchers, a chapel, a primary school, a farm shop and a train station (which was where Smiths Concrete Limited is now situated).
Currently Blackthorn has a Village Hall and is home to a few small businesses. There is no public transport to Blackthorn. Blackthorn used to have a railway station on the Chiltern Line.
Blackthorn provides 2 or 3 events annually including the village fête, a summer barbecue and often another event (in the past this has included Halloween "trick or treating" and Christmas Carols). For the Queen's Jubilee it they had their own queen who paraded around the village in a dress. The Queen of blackthorn opened the fête and greeted everyone as they came in with a good kiss on the lips.
Harlan UK is based in Blackthorn and is occasionally the target of animal rights activists.
