Comprehensive Assessment of Emergency Medical Services 101 and 911 /Communications Center Operations Study The methodologies used to project future needs; whether people, workload, or in this instance EMS call volume; will typically involve an examination of recent year trends of those same characteristics. Today of course the application of technology and various software programs are available as well; all of which also, however, will typically require historical data to feed their formulas. Subsequently, the starting point for these calculations will be the experienced (known) annual EMS call volumes for 2000 -2011 and noted in Figure 31, together with the annual County populations as documented by the North Carolina Office of Budget & Management for the same years. Between 2000 (116,106) and 2011 (135,776) the County's population increased 16.9 percent. Between 2000 (9,231) and 2011 (10,719) the County's annual EMS call volume increased 16.1 percent. While the County's total annual population figures are important, the correlation of the number of EMS calls per unit of population served; in this case the number of calls per 1,000 residents; is the variable that will be incorporated into the calculations of future annual EMS call volumes; Figure 34. As illustrated in Figure 32 the number of EMS calls per 1,000 residents of course varied from year -to- year. The ratio increased during eight (8) different years and decreased during three (3) different years. In this case the average annual change in the ratio of EMS calls /1,000 was + 3 /10ths of 1 %. This ratio was the applied to the projected future annual populations, the results of which are identified here.
