The revision was to decrease the population projection in the year 2040Klotz Associates Project No. 0972.000.000January 20106-5Caldwell County Regional Water and Wastewater Planning StudyFinal Report
to a value that was within the values of the TSDC and the TWDB. Table 6-1 hasbeen prepared to list the estimated population values developed by the TSDC andthe TWDB. It was agreed to proceed with an estimate of 100,000 in 2040 for thepurpose of this study. Accordingly, population projections used for this study arelisted in Table 6-2.GRAPH 6-4Caldwell County Population Projection Comparison120,000100,000HistoricalTWDBTSDC - Scenario 3P: 111,210Y: 204080,000P: 83,250Y: 204060,00040,00020,00001850186018701880189019001910192019301940195019601970198019902000201020202030204020502060PopulationCensus YearTABLE 6-1Population Projection EstimatesYearTexas State Data Center Population ScenariosTWDB0.0 0.5 1 2000-20072010 34,844 40,289 46,308 38,724 45,9582020 37,355 49,975 65,057 45,622 59,7222030 39,258 60,127 86,902 51,469 71,4592040 40,677 70,593 111,210 55,752 83,250Klotz Associates Project No. 0972.000.000January 20106-6Caldwell County Regional Water and Wastewater Planning StudyFinal Report
