Population statistics confirm this theory; Shenkeng's population was steadily shrinking until three years ago, when more people moved in than moved away. Shihting's rate of social population increase (the ratio between population moving out and moving in) also changed dramatically three years ago from negative 84.7 % to negative 1.85 %.
人口統計資料，也印證這個說法，一向人口外流的深坑，三年前遷入人口已超過遷出人口；石碇的社會人口增際（即遷入遷出人口比例）三年來也從負百分之八十四．七一遽降至負百分之一．八五。
