In mid-2002, the U.S. national EPR was 62.8. The BLS doesn't publish separate estimates of NYC's noninsitutional pop (a concept, by the way, that excludes the incarcerated, no small number), but we can guess at it from figures given for employment and the participation rate. Based on those estimates, were NYers employed at the national rate, there would have been nearly 500,000 more people working in 2002.
