Today, people in rich countries are linked to people in poor countries through the commoditization and consumption of what is called fashion. People work long hours in one area of the globe to produce things that people in another part of the globe are anxious to consume. An example of this is the chain of production and consumption of Nike shoes, which are produced in Taiwan and then purchased in North America. At the production end, there is nation-building a hard working ideology that leads people to produce and entices people to consume with a vast amount of goods for the offering[clarification needed]. Commodities are no longer just utilitarian but are fashionable, be they running shoes or sweat suits.
Benefits of primary research is specific information about a fashion brand's consumer is explored. Surveys are helpful tools; questions can be open-ended or closed-ended. A negative factor surveys and interviews present is that the answers can be biased, due to wording in the survey or on face-to-face interactions. Focus groups, about 8 to 12 people, can be beneficial because several points can be addressed in depth. However, there are drawbacks to this tactic, too. With such a small sample size, it is hard to know if the greater public would react the same way as the focus group. Observation can really help a company gain insight on what a consumer truly wants. There is less of a bias because consumers are just performing their daily tasks, not necessarily realizing they are being observed. For example, observing the public by taking street style photos of people, the consumer did not get dressed in the morning knowing that would have their photo taken necessarily. Through observation patterns can be seen, helping trend forecasters know what their target market needs and wants.
Although the fashion industry developed first in Europe and America, as of 2017, it is an international and highly globalized industry, with clothing often designed in one country, manufactured in another, and sold worldwide. For example, an American fashion company might source fabric in China and have the clothes manufactured in Vietnam, finished in Italy, and shipped to a warehouse in the United States for distribution to retail outlets internationally. The fashion industry has long been one of the largest employers in the United States, and it remains so in the 21st century. However, U.S. employment declined considerably as production increasingly moved overseas, especially to China. Because data on the fashion industry typically are reported for national economies and expressed in terms of the industry's many separate sectors, aggregate figures for world production of textiles and clothing are difficult to obtain. However, by any measure, the clothing industry accounts for a significant share of world economic output. The fashion industry consists of four levels:
