Geography and climate

Watersheds of Mexico.

Mexico is located at about 23° N and 102° W in the southern portion of North America. It is also located in a region known as Middle America. Almost all of Mexico lies in the North American Plate, with small parts of the Baja California peninsula on the Pacific and Cocos Plates. Geophysically, some geographers include the territory east of the Isthmus of Tehuantepec (around 12% of the total) within Central America. Geopolitically, however, Mexico is considered part of North America along with Canada and the United States.

Mexico's total area is 1,972,550 km², making it the world's 14th largest country by total area, and includes approximately 6,000 km² of islands in the Pacific Ocean (including the remote Guadalupe Island and the Revillagigedo Islands), Gulf of Mexico, Caribbean Sea, and Gulf of California. On its north, Mexico shares a 3,141 km border with the United States. The meandering Río Bravo del Norte (known as the Rio Grande in the United States) defines the border from Ciudad Juárez east to the Gulf of Mexico. A series of natural and artificial markers delineate the United States-Mexican border west from Ciudad Juárez to the Pacific Ocean. On its south, Mexico shares an 871 km border with Guatemala and a 251 km border with Belize.

Topography

Climate

Areas south of the twenty-fourth parallel with elevations up to 1,000 meters (the southern parts of both coastal plains as well as the Yucatán Peninsula), have a yearly median temperature between 24 and 28 °C. Temperatures here remain high throughout the year, with only a 5 °C difference between winter and summer median temperatures. Although low-lying areas north of the twentieth-fourth parallel are hot and humid during the summer, they generally have lower yearly temperature averages (from 20 to 24 °C) because of more moderate conditions during the winter.

Many large cities in Mexico are located in the Valley of Mexico or in adjacent valleys with altitudes generally above 2,000 m, this gives them a year-round temperate climate with yearly temperature averages (from 16 to 18 °C) and cool nighttime temperatures throughout the year.

Many parts of Mexico, particularly the north, have a dry climate with sporadic rainfall while parts of the tropical lowlands in the south average more than 200 cm of annual precipitation.

Biodiversity

In Mexico, 170,000 square kilometres are considered "Protected Natural Areas." These include 34 reserve biospheres (unaltered ecosystems), 64 national parks, 4 natural monuments (protected in perpetuity for their aesthetic, scientific or historical value), 26 areas of protected flora and fauna, 4 areas for natural resource protection (conservation of soil, hydrological basins and forests) and 17 sanctuaries (zones rich in diverse species).

The discovery of the Americas brought to the rest of the world many widely used ingredients. Some of Mexico's native ingredients include: chocolate, tomato, maize, vanilla, avocado, guava, chayote, epazote, camote, jícama, nopal, tejocote, huitlacoche, sapote, mamey sapote, many varieties of beans, and an even greater variety of chiles, such as the Habanero. Most of these names are in indigenous languages like Nahuatl.

Economy

Mexico has a free market mixed economy, and is firmly established as an upper middle-income country. It is the 12th largest economy in the world as measured in gross domestic product in purchasing power parity. According to the latest information available from the World Bank, Mexico had the second-highest Gross National Income per capita in Latin America in nominal terms, at $8,340, and the third-highest in purchasing power parity (PPP), at $12,580 in 2007. After the 1994 economic debacle, Mexico has made an impressive recovery, building a modern and diversified economy. Recent administrations have also improved infrastructure and opened competition in seaports, railroads, telecommunications, electricity generation, natural gas distribution and airports. Oil is Mexico's largest source of foreign income. According to Goldman Sachs BRIMC review of emerging economies, by 2050 the largest economies in the world will be as follows: China, United States, India, Japan, Brazil, and Mexico.

According to the director for Mexico at the World Bank, the population in poverty has decreased from 24.2% to 17.6% in the general population and from 42% to 27.9% in rural areas from 2000-2004. Nonetheless, income inequality remains a problem, and huge gaps remain not only between rich and poor but also between the north and the south, and between urban and rural areas. Sharp contrasts in income and Human Development are also a grave problem in Mexico. The 2004 United Nations Human Development Index report for Mexico states that Benito Juárez, a district of Mexico City, and San Pedro Garza García, in the State of Nuevo León, would have a similar level of economic, educational and life expectancy development to Germany or New Zealand. In contrast, Metlatonoc, in the state of Guerrero, would have an HDI similar to that of Syria.

Many of the positive effects in poverty reduction and the increase in purchasing power of the middle class are attributed to the macroeconomic stability pursued by the last two administrations. GDP annual average growth for the period of 1995–2002 was 5.1%.The economic downturn in the United States also caused a similar pattern in Mexico, from which it rapidly recovered to grow 4.1% in 2005 and 3% in 2005. Inflation has reached a record low of 3.3% in 2005, and interest rates are low, which have spurred credit-consumption in the middle class. Mexico has experienced in the last decade monetary stability: the budget deficit was further reduced and foreign debt was decreased to less than 20% of GDP. Along with Chile, Mexico has the highest rating of long-term sovereign credit in Latin America.

The remittances from Mexican citizens working in the United States account only for .2% of Mexico's economy which reaches US$20 billion dollars per year in 2004 and is the fourth largest source of foreign income after oil, industrial exports, and food exports. In 2008, US$67.5 billion dollars per year was sent by migrants in the United States to Mexico.

Ongoing economic concerns include the commercial and financial dependence on the US, low real wages, underemployment for a large segment of the population, inequitable income distribution (the top 20% of income earners account for 55% of income), and few advancement opportunities for the largely Amerindian population in the impoverished southern states. Lack of structural reform is further exacerbated by an ever increasing outflow of the population into the United States, decreasing domestic pressure for reform.
