200 Years of U.S. Immigration Looks Like the Rings of a Tree

From policy details to serious ethical issues, the entry problem in the US has become a very urgent issue in recent weeks.

However, today's immigration war has been done in a long and slowly accumulating history that is difficult to grasp from the size and complexity of the scale. Tens of millions of people representing every corner of the world have migrated to America during the past two centuries. Pictures appearing over time may be similar to living organisms that motivate this graphic.

The tree's annual growth cycle reflects various environmental conditions that are not perfect circular or elliptical. This algorithm of immigrant graphics is inspired by the regular changes and irregular shapes of these natural creatures. (Read: "Immigration crisis scenario on both sides of the border")

Like a country, trees have hundreds and thousands of years of history. The cells slowly grow, and the growth pattern affects the shape of the trunk. As these cells leave information marks on trees, new immigrants will also contribute to the shape of the country.

These immigrant "rings" expanded at a time when certain welcoming factors dominated, as the US immigration policy became less stringent and their economy provided more opportunities. During many years of war and economic turmoil, the "ring" tends to stay slim.

The origin of the immigrant population in America also changed from the times to the times. During the 1840s and 1880s, European immigrants came mainly from north and western Europe, and the entrance to Ellis Island principally represented a large inflow of the early 20th century from the south and eastern Europe. Between 1970 and 2000 immigrants from Asia increased, large immigrants in Latin America started in 1950 and lasted half a century. Initial US census data ignored the population of slave and indigenous communities, but African immigrants only appeared in the 21st century.

During the colonial rule of the United States over 200 years ago, colonialists began flowing from the middle of America to America (America). Even in the early days of the United States, formal policies on informal law and immigration began to determine the demographic profile of the population (Zolberg, 2006). Only in 2014, about 1.7 million immigrants came from the United States. Mexico, China, India, the Caribbean Sea, of which 1 million were lawful permanent resident (LPR) (US Department of Homeland Security, 2016).

Two hundred years ago, the first immigrants came to the country of the United States. The United States is based on the concept of immigration, but discussion on how immigration policy is implemented continues. Controversy: How should the United States and Mexico handle legal and illegal immigration issues? More and more immigrants arrive illegally and seeking a better life. In the past 15 years, a significant increase in illegal entry has been brought to the United States. - 'Labor debate:'; American dream of revisiting immigrants is a topic in modern dialogue. Many people believe immigrants coming to America are getting a very necessary job from happy Americans. On the other hand, there are still people who believe that the job deprived is not a work for Americans to run because of poor working conditions, low wages, and lack of medical insurance.

For many years well-known conservatives have argued that they like legitimate immigrants and prefer only illegal immigrants. This is empty for those who keep a bill that reduces legal immigration to half. Clearly, some of the most prominent voices in this field are themselves immigrant or immigrant children. For conservatives who believe in free trade and globalization, this is a good opportunity to understand the benefits of immigrants. Several people on the right are open to hostile or passive attacks against legal immigration for a long time. However, other people have recently shifted this problem and became foolish about keeping immigrants. This is because the playing card is not only the nominal chief of G.O.P. Unless things change, he is the future. Those who dislike this idea should talk about past, present and future immigrants.
