cannot work. The poverty rate of people between the ages of 18 to 64 was 10.7%, or 21.1 million people. Of these, nearly half, 5.1%, were working at least part-time. Using the US Census Bureau's definition of poverty, the working poverty rate seems to have remained relatively stable since 1978. There is quite a bit of controversy around this measurement, namely how the dollar amounts that make up the poverty threshold are calculated. In 1961, the Department of Agriculture came out with an "economy food plan" to be used as a temporarily during an emergency or when a family is in need. This plan did not account for any food consumption outside of the home, and while it was considered nutritious, it was limited in variety and monotonous, thus the temporary designation. The US government took this number and—because the average family at the time spent one-third of their income on food—multiplied it by three. This has remained the standard way to set the poverty thresholds. The food plan has not changed, it has only been adjusted for inflation. One argument is that this is no longer an accurate way to measure poverty because the average lifestyle has changed dramatically since the 1960s US compared to Europe Other high-income countries have also experienced declining manufacturing sectors over the past four decades, but most of them have not experienced as much labor market polarization as the United States. Labor market polarization has been the most severe in liberal market economies like the US, Britain, and Australia. Countries like Denmark and France have been subject to the same economic pressures, but due to their more "inclusive" (or "egalitarian") labor market institutions, such as centralized and solidaristic collective bargaining and strong minimum wage laws, they have experienced less polarization. Cross-national studies have found that European countries' working poverty rates are much lower than the US's. Most of this difference can be explained by the fact that European countries' welfare states are more generous than the US's. The relationship between generous welfare states and low rates of working poverty is elaborated upon in the "Risk factors" and "Anti-poverty policies" sections. The following graph uses data from Brady, Fullerton, and Cross (2010) to show the working poverty rates for a small sample of countries. Brady, Fullerton, and Cross (2010) accessed this data through the Luxembourg Income Study. This graph measures household, rather than person-level, poverty
