Model 1

The table shows the changes in ethnic population groups in Atlantis City over a twenty-year period. Overall, the city population grew significantly and all ethnicgroups grew in size, but the percentages of each group changed considerably. There was a massive reduction in the percentage of Caucasians, which decreased by about one third, from 68% in 1988, to 59% in 1998 and 47% in 2008, although their numbers increased from 60,000 to 72,000. The Indian population stayed relatively stable for the first decade and then more than trebled from 2,500 to 8,500, in the decade from 1998 to 2008, even though it remained the smallest group in the city. The Polynesians and South East Asians had a similar growth pattern, increasing from 18% and 12% respectively in 1988 to 24% and 23% of the population in 2008, although the South East Asian population, which grew from 11,000 in 1988 to 35,000 in 2008, had a greater percentage increase.
