<u>Answer</u>:
Since the mid 1970s, the United States had a significant trade deficit.
<u>Explanation</u>:
The U.S had undergone a trade deficit since the 1970s. This has been contributed to the fact that they have been importing way more supplies and goods than the other countries were buying from the Americans. These imports have affected the native industries. Also, the demand for American products went down drastically and thus contributing to the deficit.
While Europe and Great Britain undertook industrialization in the 18th century, Americans started it in the 19th century-this delay resulted in the US depending upon imported goods and also in US struggling to meet Europe's levels of export.
Today, a majority of the world’s population<span> lives in cities</span>. By 2050, two-thirds of all people on the planet are projected to call urbanized areas their home. This trend will be most prominent in developing countries in Africa, Asia and Latin America: More than 90% of the global urban growth is taking place in these regions, adding 70 million new residents to urban areas every year.
For the many poor in developing countries, cities embody the hope for a better and more prosperous life. The inflow of poor rural residents into cities has created hubs of urban poverty. One-third of the urban population in developing countries<span> resides in slum conditions</span>. On the other hand, urban areas are engines of economic success. The 750 biggest cities on the planet account for 57% of today’s GDP, and this share is projected to rise further. It is thus unsurprising that rapid urban growth has been dubbed one of the biggest challenges by skeptics and one of the biggest opportunities by optimists.
One reason for this disagreement is that the relationship between economic development and urbanization is complex; causation runs in both directions. In the study “Growing through Cities in Developing Countries,” published in the World Bank Research Observer, Gilles Duranton from the University of Pennsylvania examines this relationship in depth. The strong positive correlation between the degree of urbanization of a country and its per-capita income has long been recognized. Still, the relationship between these two variables is only partially understood in the context of developing countries. In reviewing studies that focus on the impact of cities both in developed and developing countries, Duranton tries to identify the extent to which urbanization affects economic growth and development. (“Agglomeration” economies refers to physical clustering.

A follower of structural-functionalism would look at the college classroom as an institution, and try to find what holds it together. He would analyze tertiary education is an important factor in today's society, and why college classroom s are the means to access tertiary education.
