Currently, the United States is among the nations receiving the highest number of immigrants. Comparing the U.S immigration to other countries such as Canada, it is evident that Canada admits a far higher educated immigrant population compared to the United States. There are major differences in the immigration policies of the U.S and other countries. While the United States admits immigrants based on family ties, countries like Canada mainly admits most immigrants by putting consideration on employment-related credentials. Immigration into the U.S affects the population by increasing social ties and creating cultural diversity. In other countries like Canada, immigration mainly affects the job market by increasing the number of qualified personnel. Immigration from the southern side of the United States negatively affects the states involved due to high number of illegal immigrants from Mexico. Further, uncontrolled immigration can lead to straining of social amenities such as health since due to lack of documentation. Immigration into the United States also affects the economy by increasing the number of unskilled laborers into the country ( Kaushal & Lu, 2015) . As a result, most immigrations take up informal jobs.
The U.S is responding to immigration by ensuring there are more stringent rules on the requirements needed from immigrants. Further, the Trump administration is fighting illegal immigration occurring from Mexico by building a wall at the U.S border with Mexico ( Lessem, 2013) . Other countries like Mexico have not done much to respond to issues of immigration since they do not have a high number of immigrants. Countries like Cuba have also responded to immigration by developing policies that offer more strict measures on the requirements that immigrants need to meet. Remarkably, Canada has responded to immigration by improving most of their academic qualifications for immigrants.

The effect of population growth and social change is mutually related. For example, population changes that include an increase in birth results to increase in the working age of the population, which in turn leads to social changes like the increase in unemployment. Social changes like improvement in healthcare and the spread of education affect population factors such as fertility rates and low mortality and higher life expectancy (Beard, & Bloom, 2015) . Urbanization also leads to population changes despite the effects of its high levels. Population and social changes are said to be an indication of the social, economic, and political changes of any particular society.
Population change is one of the trends in modern day social change. Diverse processes from different parts of the world are involved. World population is currently growing at a faster rate. By the end of the century, the global population will have doubled from what it was at the start of the century. Most of the world's population is aging, and this presents opportunities and challenges (Anson, Bartl, & Kulczycki, 2019) . An aging population is associated with a shrinking workforce, a demand for healthcare, social pensions, and social care. Many countries are experiencing population decline. Even though population decline is not typical in most of the states, its relevance will suffice in the future.
Social changes have had a significant impact on world population. In developed countries, there has been a fall in fertility rates leading to population decline. Immigration of people can help in improving the natural population, but it can be detrimental as it can result in drastic social changes. ( Anson, Bartl, & Kulczycki, 2019) . On the other hand, in developing countries, the population has continued to overgrow, leading to urbanization that surpasses the capacity that can be absorbed using the available resources.
