The history and commerce of Newfoundland and Labrador was built on the fishery and thus many small communities were established throughout the entire coastal region. Some of these communities were seasonal fishing stations and some eventually grew into communities which were very much isolated from much of the country except for water transportation or overland hiking trails. In many communities the seasonal inshore cod fishery provided both sustenance and the vast majority of employment opportunities. In the early 20th century, settlement patterns and population distribution were changing due to a number of factors. Newfoundlanders began moving to larger centres such as
St. John's. For example, in 1874, the population of St. John's was 30,574 and the major
Conception Bay districts had a combined population of 41,368. By 1935, the population of the Conception Bay districts had increased by over 4,500 people, while the population of St. John's had more than doubled to 65,256 people. Other parts of the island and
Labrador went through major changes in resource development that affected areas outside the
Avalon Peninsula. The construction of paper mills in both
Grand Falls and
Corner Brook drew many people from coastal towns and villages. These areas contributed to growth in other areas such as
Botwood and
Deer Lake. Mineral discoveries at places such as
Wabush and
Labrador City,
St. Lawrence,
Baie Verte and
Buchans also contributed to the movement of people away from the outports.
World War II also had a part to play when air force bases were built at
Stephenville,
Argentia and
Goose Bay, and the booming international airport in
Gander. The
1992 cod moratorium especially affected Newfoundland's rural
outports, where the loss of an important source of income caused widespread out-migration. Some communities have tried to compensate by fishing shellfish, crab and shrimp, but their stocks are faltering in recent years. The ever-shrinking communities are struggling with an aging population that needs access to essential services. As of October 2017, the province's marine transportation system costs $76 million annually. It is often cited as a burden to the economy, requiring spending millions of dollars to guarantee frequent transport from communities with no more than a hundred residents. ==Prior to 1954==
