Jersey's population has risen and fallen again many times over the centuries, culminating in the steady growth during the 20th and 21st centuries, interrupted only by the two World Wars. Estimates of population in past centuries are fairly rudimentary, consisting of counting the numbers of properties shown on maps and multiplying by a factor of the estimated number of people per property.
Even the early censuses were not particularly reliable, those taken in 1781 and 1815 amounting only to a muster of those men liable for Militia service. The first reliable census was taken in 1821, and this appears to have just been a count of inhabited properties and the people living in them, with no names recorded.
