Benjamin Disraeli, the famous nineteenth century prime minister, said, "London is not a city, - it is a nation." Today this is an understatementLondon, with its vast range of different ethnic groups, is a world. Certainly, London is the most culturally diverse city in the world. The city was founded by the Romans and since then new arrivals have constantly added to its character and prosperity. Within 10 years 40% of Londoners will be from ethnic minority groups, including the growing number of Londoners of mixed ethnic origin, but most of them will have been born in Britain. Children of Caribbean-Chinese marriages will go to school with children of Russian-Irish couples. None of them will be English but all of them will be Londoners. Most of Britain's ethnic minority residents live in the capital, speaking over 300 languages. Nearly all of the African population and many of the Caribbean population of Britain live in London (83% and 58% respectively)39% of the Chinese population of Britain and 36% of the Asian population of Britain live in London. The largest migrant community is from the Irish Republic with 256,000 people, 3.8% of the total population of London. There are an estimated 330,000 refugees and asylum seekers living in London, with most recent arrivals coming from Eastern Europe, North Africa and Kurdistan. Young people, in particular, are skilled at dealing with a large number of different and hybrid cultures. They themselves often have several different ethnic identities since their parents and grandparents may come from several different backgrounds and their friends and partners do also. They are "skilled cross-cultural travelers" without leaving their home-town.

The world’s population continues to grow. There now are about 4 billion of us on earth. That could reach 6 billion by the end of the century and 11 billion in a further 75 years. Experts have long been concerned about such a growth. Where will we find the food, water, jobs, houses, school and health care for all these people?

A major new study shows that the situation may be changing. A large and rapid drop in the world’s birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations.

Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from home instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population grow.

China is one of the nations that have made great progress in reducing its population growth. China has already cut its rate of population growth by about half since 1970.

Each Chinese family is now urged to have no more than one child. And the hope is to reach a zero population growth with the total number of births equaling the total number of deaths by the year 2000.

Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.
