     584 Asians 

     124 Africans 

     95 Eastern and Western Europeans

     84 Latin Americans

     55 former Soviets ( including Lithuanians, Latvians, Estonians, and other national groups)

     52 North Americans 

     6 Australians and New Zealanders The people of the village would speak:

     165 Mandarin

     86 English 

     83 Hindu/Urdu 

     64 Spanish

     58 Russian

     37 Arabic

     The above list covers the mother tongues of only half the village.

      One-third of the people in the village are children, and only 60 are over the age of 65. Just under half

of the married women in the village have access to modem equipments.

     This year 28 babies will be bom. Ten people will die, 3 of them for lack of food, 1 from can-cer. Two

of the deaths will be of babies bom within the year. With the 28 births and 10 deaths, the population of the

village next year will be 1,018.

      In this village of 1,000 persons, 200 people receive 75 percent of the income; another 200 re-ceive only

2 percent of the income.

     About one-third have access to clean, safe drinking water.

     Of the 670 adults in the village, half can not read nor write.

      The village has a total yearly budget (预算), public and private, of over $3 million-$ 3,000 per person if

it is distributed evenly. Of the total $3 million:

     $ 181,000 goes to weapons and warfare

     $ 159,000 to education

     $ 132,000 to health care

      These weapons are under the control of just 100 of the people. The other 900 are watching them with

deep anxiety, wondering whether they can learn to get along together.
