POPULATION GROWTH
Population development in Lewisville City from 1960 to 1994 was characterized by alternate large and small increases. Nineteen-ninety showed a 6% decrease. In 1991 the population rebounded by 21%, slowed to 1% the next year, and, then decreased 13% in 1993. The Idaho Department of Health and Welfare Center for Vital Statistics and Idaho Department of Commerce population statistics from 1990 through 1994 indicate a period of growth, although the percentage of growth varies greatly from year to year. Between 1990 and 1994, the population increased 42%.

POPULATION COMPARISON
The two cities closest to Lewisville in size, population, and general characteristics are Ririe and Roberts. In 1980 Lewisville was larger than Roberts, but fell behind in population by 1990. By 1993 the population of the two cities was about the same. Statistics show all three cities have had steady growth since 1980. Although Ririe remains the largest of the three cities, Roberts and Lewisville have reached populations near Ririe’s.

AGE
According to 1990 Census records, more than half the population is between the ages of 25 and 65.
This is about the same percentage of adults the same age group in Jefferson County, but a little less than the state’s percentage. About 40% of Lewisville’s population are children less than 18. Seven percent of the population are young adults, and senior citizens comprise 8.5% of the population.

POPULATION FORECAST
If the 1990 statistics were projected forward seven years and the population was to remain the same, the number of people in the various age groups would increase significantly. The thirty-five (35) ten and eleven-year-old children would be 17 and 18 years old in 1997. There were nineteen (19) children that age in 1990, increasing the number of 17 and 18-year-old young adults requiring city services by 184%. The number of 19 and 20-year-old people would increase by 310%, and the number of young adults 19 to 25 would increase 333%. Because older age designations were grouped differently, it is difficult to compare them. These statistics do not consider the number of people moving in or out of the city, the number of children born to parents in Lewisville, or the 42% increase in population since 1990. Lewisville is clearly experiencing a period of rapid growth, and comparisons with the state, county, and other similar cities seem to confirm significant population increases with the need for expanded city services directed to children and young adults.
