Maui population growth

Maui’s population is growing more quickly than the population of Hawaii and the rest of the United States. Between 2010 and 2016, the number of people living in Maui increased by 6.8%, compared to an increase of 5.0% across Hawaii, and 4.7% across the United States as a whole.

Maui’s population suffered a decline during the 1940s and 1950s, in part because of the impact of the Second World War. Once growth resumed in the 1970s, though, it was explosive. Between 1970 and 1990, the number of Maui residents more than doubled – from just under 46,000 people in 1970 to just over 100,000 people in 1990. Growth since then has slowed to a more manageable rate, although it is still very healthy.
