OCCUP Outlook Q. 1989 Summer;33(2):8-17.
America is a mobile society, and the mobility is evident in the jobs people hold. From one year to the next, almost 1 worker in 5 enters or returns to an occupation that they did not work in 12 months earlier. A worker's age, sex, race, and ethnicity influence the likelihood of changing occupations.
美国是一个流动性很强的社会，这种流动性在人们所从事的工作中体现得很明显。从一年到下一年，几乎每5名工人中就有1人进入或重新回到他们在12个月前未曾从事过的职业。工人的年龄、性别、种族和民族会影响其更换职业的可能性。
