Job counts are BLS OEWS survey estimates built from three years of samples, so moves of a few percent from one year to the next are within the survey's margin. Self-employed tradespeople are not counted. Areas with fewer than 3,000 jobs or a large sampling error are shown as a single figure rather than a trend.
