Question: Indigenous peoples of Mexico (Spanish: pueblos indigenas de Mexico), Native Mexicans (Spanish: nativos mexicanos), or Mexican Native Americans (Spanish: nativo america mexicanos), are those who are part of communities that trace their roots back to populations and communities that existed in what is now Mexico prior to the arrival of Europeans. According to the National Commission for the Development of Indigenous Peoples (Comision Nacional para el Desarrollo de los Pueblos Indigenas, or CDI in Spanish) and the INEGI (official census institute), in 2015, 25,694,928 people in Mexico self-identify as being indigenous of many different ethnic groups, which constitute 21.5% of Mexico's population.

Generally, indigenous Mexicans live more poorly than non-indigenous Mexicans however, social development varies between states, different indigenous ethnicities and between rural and urban areas. In all states indigenous people have higher infant mortality, in some states almost double of the non-indigenous populations.  Some indigenous groups, particularly the Yucatec Maya in the Yucatan peninsula and some of the Nahua and Otomi peoples in central states have maintained higher levels of development while indigenous peoples in states such as the Guerrero or Michoacan are ranked drastically lower than the average Mexican citizen in these fields. Despite certain indigenous groups such as the Maya or Nahua retaining high levels of development, the general indigenous population lives at a lower level of development than the general population.  Literacy rates are much lower for the indigenous, particularly in the southwestern states of Guerrero and Oaxaca due lack of access to education and a lack of the educational literature available in indigenous languages. Literacy rates are also much lower, with 27% of indigenous children between 6 and 14 being illiterate compared to a national average of 12%. The Mexican government is obligated to provide education in indigenous languages, but many times fails to provide schooling in languages other than Spanish. As a result, many indigenous groups have resorted to creating their own small community educational institutions.  The indigenous population participate in the workforce longer than the national average, starting earlier and continuing longer. A major reason for this is that significant number of the indigenous practice economically under productive agriculture and receive no regular salaries. Indigenous people also have less access to health care.

Using a quote from the above article, answer the following question: How did the economic work?

Answer: The indigenous population participate in the workforce longer than the national average, starting earlier and continuing longer.


Question: Cullen was born in Hamilton, Lanarkshire. His father William was a lawyer retained by the Duke of Hamilton as factor, and his mother was Elizabeth Roberton of Whistlebury. He studied at the Old Grammar School of Hamilton (renamed in 1848 The Hamilton Academy), then, in 1726, began a General Studies arts course at the University of Glasgow. He began his medical training as apprentice to John Paisley, a Glasgow apothecary surgeon, then spent 1729 as surgeon on a merchant vessel trading between London and the West Indies.

In 1755 he was enticed by Lord Kames to become Professor of Chemistry and Medicine at the University of Edinburgh. It was in Edinburgh, in 1756, that he gave the first documented public demonstration of artificial refrigeration. Cullen used a pump to create a partial vacuum over a container of diethyl ether, which then boiled, absorbing heat from the surroundings. This created a small amount of ice, but the process found no commercial application.  From 1757 he delivered lectures on clinical medicine in the Edinburgh Royal Infirmary. On the death of Charles Alston in 1760, Cullen at the request of the students undertook to finish his course of lectures on materia medica; he delivered an entirely new course, notes of which were published in an unauthorised edition in 1771, but which he re-wrote and issued as A Treatise on Materia Medica in 1789.  On the death of Robert Whytt, the professor of the institutes of medicine, Cullen accepted the chair, at the same time resigning that of chemistry. In the same year he had been an unsuccessful candidate for the professorship of the practice of physic (medicine), but subsequently an arrangement was made between him and John Gregory, the successful candidate, by which they both agreed to deliver alternate courses on the theory and practice of medicine. This arrangement continued until the sudden death of Gregory in 1773. Cullen was then appointed sole professor of the practice of physic, and he continued in this office until a few months before his death.  In 1783 Cullen (together with his sons) was a co-founder of the Royal Society of Edinburgh.  He died on 5 February 1790 in Kirknewton, West Lothian, and is buried in the churchyard there. His son Robert lies with him.
