St. Kitts and Nevis is heavily dependent upon tourism to drive its economy, a sector which has expanded significantly since the 1970s. In 2009 there were 587,479 arrivals to Saint Kitts compared to 379,473 in 2007, an increase of just under 40% in a two-year period, however the tourist sector decreased during the Global financial crisis and has only recently returned to pre-crash levels. In recent years the government has sought to diversify the economy via agriculture, tourism, export-oriented manufacturing, and offshore banking.
