As the economy improves and consumers feel more confident about spending, advertisers and marketers are seeing increased interest among clients.

Indeed, consumers are spending again. Retail sales were up 4.7% in February compared with 12 months earlier, according to the Census Bureau. Auto sales grew 8.8% and non-store retail sales, including e-commerce, direct and catalogue sales, jumped 15.7%.
While that has helped boost pay among advertisers and marketers, it has done little to boost hiring, which slowed in the first quarter, according to PayScale.
A CNNMoney analysis of Census data shows these jobs -- which have roughly the same amount of men and women workers -- have little disparity in salaries.
