monitored. Youth unemployment rates tend to be higher than the adult rates in every country in the world. Older age workers Those older than the statutory defined retirement age may continue to work, either out of enjoyment or necessity. However, depending on the nature of the job, older workers may need to transition into less-physical forms of work to avoid injury. Working past retirement age also has positive effects, because it gives a sense of purpose and allows people to maintain social networks and activity levels. Older workers are often found to be discriminated against by employers. Working poor Employment is no guarantee of escaping poverty, the International Labour Organization (ILO) estimates that as many as 40% of workers are poor, not earning enough to keep their families above the $2 a day poverty line. For instance, in India most of the chronically poor are wage earners in formal employment, because their jobs are insecure and low paid and offer no chance to accumulate wealth to avoid risks. According to the UNRISD, increasing labor productivity appears to have a negative impact on job creation: in the 1960s, a 1% increase in output per worker was associated with a reduction in employment growth of 0.07%, by the first decade of this century the same productivity increase implies reduced employment growth by 0.54%. Both increased employment opportunities and increased labor productivity (as long as it also translates into higher wages) are needed to tackle poverty. Increases in employment without increases in productivity leads to a rise in the number of "working poor", which is why some experts are now promoting the creation of "quality" and not "quantity" in labor market policies. This approach does highlight how higher productivity has helped reduce poverty in East Asia, but the negative impact is beginning to show. In Vietnam, for example, employment growth has slowed while productivity growth has continued. Furthermore, productivity increases do not always lead to increased wages, as can be seen in the United States, where the gap between productivity and wages has been rising since the 1980s. Researchers at the Overseas Development Institute argue that there are differences across economic sectors in creating employment that reduces poverty. 24 instances of growth were examined, in which 18 reduced poverty. This study showed that other sectors were just as important in reducing unemployment, such as manufacturing. The services sector is most effective at translating
