25aAppendix Dthe change in that ratio between 2000 and 2006. Thus, hisanalysis focused on the changes in the composition of thepopulation, not in the size of the population. (Id. at 62.) Toevaluate changes in the composition of Irving’s populationbetween 2000 and 2006, he compared the Hispanic andnon-Hispanic share of CVAP for Irving as reported in the2000 Census and the 2006 ACS. He found that the dataexamined indicated major changes-with an increase intotal Hispanic population in Irving from 31.2% in 2000 to41.7% in 2006. He also determined that the annual growthrate for Irving’s HCVAP between 2000 to 2006 was 4.4%and the average annual rate for non-Hispanic CVAP was-2.2%. He therefore concluded that the 2000 Census datawas no longer valid and determined that the 2006 ACSdata far more accurately reflected current demographicconditions.Mr. Ely then prepared estimates of the 2008Hispanic and non-Hispanic percentages of CVAP for usein constructing his illustrative districts. (Id. at 62.) Todo this, Mr. Ely computed growth rates for each of thecomponent populations based on the 2000 Census and2006 ACS city-wide data (4.4% for HCVAP and -2.2%for non-Hispanic CVAP). He used city-wide figures forethnicity and age, and Census tract level information forcitizenship status. (PL’s Ex. 1, at 7.) He then extrapolatedthat growth rate until 2008, which was applied to theillustrative districts to arrive at an estimated percentageof HCVAP in the illustrative district in 2008. (Id. at 8.)Mr. Ely did not use 2006 ACS data to estimate theactual, current population in the illustrative districts. In
