Gibraltar records

Nationalarchives.gi, the website of the Gibraltar National Archives, includes details of the registers of population (census) of Gibraltar going back to 1777.  Population lists and registers for 1777, 1791, 1814, 1816, 1817, 1834, 1868, 1871, 1878, 1881, 1891 1901, 1911 and 1914 are now online for free.
The later more detailed censuses show the name of each resident, their nationality, occupation and other relevant information. Images of originals are not online.
Browsing the surnames shows a mix of a majority Spanish and a large minority of English. Gibraltar has been formally part of the British Empire since the Treaty of Utrecht of 1713. An embarrassingly large majority of the population have voted to reject Spanish claims to the territory; Spain apparently does not see any parallel with that country's enclaves of Cueta and Melilla in Morocco or Llívia in France.
