Median household income sharply increased in 2015 by 5.2% but only grew by 1.8% in 2017 to $61,372. What was the median income in 2016? What is the total difference in growth (5.2% to 1.8%) from 2015 to 2017? A census report said that 28.5 million people, or 8.8% of the population, lacked health insurance for all of 2017. Use this information to compute the total population.
