title: Unemployment in the United States
paragraph_text: During the 1940s, the U.S Department of Labor, specifically the Bureau of Labor Statistics (BLS), began collecting employment information via monthly household surveys. Other data series are available back to 1912. The unemployment rate has varied from as low as 1% during World War I to as high as 25% during the Great Depression. More recently, it reached peaks of 10.8% in November 1982 and 10.0% in October 2009. Unemployment tends to rise during recessions and fall during expansions. From 1948 to 2015, unemployment averaged about 5.8%. There is always some unemployment, with persons changing jobs and new entrants to the labor force searching for jobs. This is referred to as frictional unemployment. For this reason, the Federal Reserve targets the natural rate of unemployment or NAIRU, which was around 5% in 2015. A rate of unemployment below this level would be consistent with rising inflation in theory, as a shortage of workers would bid wages (and thus prices) upward.

paragraph_text: In the 1970s, job losses due to industrial restructuring caused New York City to suffer from economic problems and rising crime rates. While a resurgence in the financial industry greatly improved the city's economic health in the 1980s, New York's crime rate continued to increase through that decade and into the beginning of the 1990s. By the mid 1990s, crime rates started to drop dramatically due to revised police strategies, improving economic opportunities, gentrification, and new residents, both American transplants and new immigrants from Asia and Latin America. Important new sectors, such as Silicon Alley, emerged in the city's economy. New York's population reached all-time highs in the 2000 Census and then again in the 2010 Census.
title: Full employment
paragraph_text: The 20th century British economist William Beveridge stated that an unemployment rate of 3% was full employment. For the United States, economist William T. Dickens found that full - employment unemployment rate varied a lot over time but equaled about 5.5 percent of the civilian labor force during the 2000s. Recently, economists have emphasized the idea that full employment represents a ``range ''of possible unemployment rates. For example, in 1999, in the United States, the Organisation for Economic Co-operation and Development (OECD) gives an estimate of the`` full - employment unemployment rate'' of 4 to 6.4%. This is the estimated unemployment rate at full employment, plus & minus the standard error of the estimate.
