How many aristocrats are there in great Britain?

As of now, there is no official count of aristocrats in Great Britain, as the definition can vary and many titles are hereditary. However, it is estimated that there are around 700 hereditary peers with titles, along with a number of life peers, who are appointed and not hereditary. The House of Lords, where many of these aristocrats may sit, currently has around 90 hereditary peers, as the rest are life peers appointed for their lifetime. The concept of aristocracy in Britain continues to evolve and is not strictly defined by title alone.
