Premise: Boston . The city is the economic and cultural anchor of a substantially larger metropolitan area known as Greater Boston , a Metropolitan Statistical Area ( MSA ) home to a census-estimated 4.7 million people in 2014 and ranking as the tenth-largest such area in the country . Households in the city claim the highest average rate of philanthropy in the United States ; businesses and institutions rank among the top in the country for environmental sustainability and investment . The city has one of the highest costs of living in the United States as it has undergone gentrification , though it remains high on world livability rankings .
Hypothesis: Boston remains high on some rankings.
