【正文】 n people in the United States were born in another country. Of the 31 million foreign born, the largest part, percent are from Mexico. The next largest group, from the Philippines, number percent.Another way of looking at the population is by geographical distribution. Do you have any idea which states are the five most populous in the United States? Well, I’ll help you out there. The five most populous states, with population figures, are California, with almost 34 million。 and Illinois with million people. Did you get all those figures down? Well, if not, I’ll give you a chance later to check your figures. Well, then, let’s move on. All told, over half, or some 58 percent of the population, lives in the South and in the West of the United States. This figure, 58 percent, is surprising to many people. It is surprising because the East is more densely populated. Nevertheless, there are more people all together in the South and West. To understand this seeming contradiction, one need only consider the relatively larger size of many southern and western states, so although there are more people, they are distributed over a larger area. To finish up this section on geographical distribution, consider that more than threequarters of the people live in metropolitan areas like Los Angeles, New York, Chicago, and Houston. That means that only 20 percent, or 2 out of 10 people, live in rural areas. An interesting side note is that some 3,800,000 . citizens live abroad, that is, in foreign countries.Before we finish today, I want to discuss the distribution of the . population in terms of age and sex. Just for interest, would you say there are more men or more women in the United States? Well, according to the 2000 census, there are more women. In fact, there are more than five million more women than men in the . population. If we consider that more males than females are born each year, how can this difference be explained? Well, for a variety of plicated reasons that we can’t go into here, there is a progressively higher death rate for males as they get older. This is seen in 2003 life expectancy figures: the life expectancy for women is years whereas for men it is only years. I don’t know how these life expectancy figures pare to those in your countries, but statistically women generally live longer than men worldwide. Now, to finish up, let’s look at the average age of the whole population. Overall, the average age of the population is increasing: from years in 1990 to years in 2000. The average age has been slowly, but steadily, increasing over the past several decades. This trend toward a higher average age can be explained by a decreasing birth rate and an increasing life expectancy for the population as a whole. Well, I’d like to investigate these two subjects further, but I see our time is up, so we’ll have to call it quits for today. You may want to pursue the topic of the aging . population further, so there are some suggestions at the end of the lesson to help you do so. Thank you.Chapter Two Immigration: Past and PresentThe act of immigrating, or ing to a new country to live, is certainly nothing new. Throughout history, people have immigrated, or moved to new countries, for many different reasons. Sometimes these reasons were economic or political. Other people moved because of natural disasters such as droughts or famines. And some people moved to escape religious or political persecution. No matter what the reason, most people do not want to leave their native land and do so only under great pressure of some sort, but a few people seem quite adventuresome and restless by nature and like to move a lot. It seems both kinds of people came to America to live. The subject of immigration is quite fascinating to most Americans, as they view themselves as a nation of immigrants. However, the early Britons who came to what is today the United States considered themselves “settlers” or “colonists,” rather than immigrants. These people did not exactly think they were moving to a new country but were merely settling new land for the “mother country.” There were also large numbers of Dutch, French, German, and ScotchIrish settlers, as well as large numbers of blacks brought from Africa as slaves. At the time of independence from Britain in 1776, about 40 percent of people living in what is now the United States were nonBritish. The majority of people, however, spoke English, and the traditions that formed the basis of life were mainly British traditions. This period we have just been discussing is usually referred to as the Colonial Period. Today, we’re a little more interested in actual immigration after this period. Let’s first look at what is often called the Great Immigration, which began about 1830 and ended in 1930. Then let’s consider the reasons for this socalled Great Immigration and the reasons it ended. Finally, let’s talk about the immigration situation in the United States today,As I said, we’ll begin our discussion today with the period of history called the Great Immigration, which lasted from approximately 1830 to 1930. It will be easier if we look at the Great Immigration in terms of three major stages, or time periods. The first stage was from approximate1y 1830 to 1860. Now, before this time, the number of immigrants ing to the United States was paratively small, only about 10,000 a year. However, the rate began to climb in the 1830s when about 600,000 immigrants arrived. The rate continued to climb during the 1840s with a tota1 of 1,700,000 people arriving in that decade. The rate continued to climb, and during the 1850s 2,600,000 immigrants arrived. During this first stage of the Great Immigration, that is, between the years 1830 and 1860, the majority of immigrants came from Germany, Great Britain, and Ireland. Now let’s consider the second stage of the Great Immigration. The second stage was from l860 to 1890, during which time another 10,000,000 pe
