At work, Quintos is finding it easier to land customers. In the past couple of months, businesses that have asked about his services have been more likely to follow through and hire him. A year ago, most were wary.
"I've had more work than I can handle," Quintos said. As a result, his firm hired a web designer last week.
The Conference Board found that optimism is growing mostly among those earning more than the median household income of roughly $50,000. For those households, the confidence index jumped to 95.1 from 85.3.
Among most other income groups, confidence either rose more slowly or fell. For those earning $15,000 to $24,999, for example, the confidence index rose modestly, from 52.6 to 55.9. And for those earning $25,000 to $34,999, it slipped from 59.8 to 57.9.
Economists say the disparity points to the gain in stock prices, which mostly benefits more affluent Americans.
Consumers' outlook on the job market also improved last month. The percentage who said jobs are plentiful rose, and the percentage who said they're hard to find declined. Economists say the shift suggests that the pace of hiring could pick up.
The economy has added an average of 208,000 jobs a month since November. That's well above the monthly average of 138,000 during the previous six months. The job growth has helped reduce the unemployment rate to a four-year low of 7.5 percent.
Some of the decline in unemployment is due to fewer people looking for work. The government counts people as unemployed only if they're actively searching for a job.
