These three policies were among the most highly supported by the Cubans interviewed in the survey, done by the independent research group NORC at the University of Chicago. Eight of 10 Cubans interviewed felt tourism to the country should be increased, and 95 percent said having a high level of economic growth was an extremely or very important goal.

And yet Cubans seemed to have little faith in their government’s capacity to deliver on those goals. Only three in 10 felt the economy would improve in the next three years. And just 13 percent said the current economy was good or excellent. Three-quarters of Cubans believed they must be careful in saying what they think, at least sometimes.

Over half of those Cubans interviewed said they would like to leave the country if given a chance, and 70 percent of those individuals said they would move to the United States if they could.

The interviews were conducted in person in October and November, before the inauguration of President Trump, who has threatened to rescind President Obama’s 2014 decision to restore diplomatic ties between the nations.

While Mr. Trump has remained relatively quiet about Cuba since taking office, his administration announced it is conducting a full review of the policy and could decide to cut off ties again.
