Due historically to a third of Bermuda's manpower being at sea at any one time, and to many of those seamen ultimately settling elsewhere, especially as the Bermudian maritime industry began to suffer, the colony was noted for having a high proportion of unmarried women well into the 20th century.
Imperial Airways and Pan-American World Airways both began flying to Bermuda in the 1930s (by which time the summer had become more important for tourists making briefer visits).
