The growth stability index measures how stable the population growth has been during the past two years in an area. The closer to 1 the index is the higher likelihood the growth trend will continue. 2024-2025 Enrollment and Demographics Study © Business Information Services, LLC Page 45 Figure 74. The expected value index measures how closely the population growth in an area for the last year equals what was expected to occur during the previous year. If a value is close to 1, then that means the population growth occurred exactly at the rate it was expected. A value greater than 1 means the growth is occurring faster than expected. Negative values mean the area is not growing at the level expected the previous year. Figure 75. Average salaries for varying industry occupations at the local level are applied to the workers in those occupations for each block group. Then the block group’s overall average salary is com- pared to the national average to form an index related to worker pay at the local level. The red areas have workers who earn more than 20 percent higher than the national average for those occupa- tions. School District of Clayton © Business Information Services, LLC Page 46 Figure 76. The diversity index measure the diversity of any population in which each person belongs to a unique race. A value of 1 indicates there is only one race represented in each Census block area. The lower the index, the more racial diversity exists.

A value of 1 indicates there is only one race represented in each Census block area.
