occupied by India, as well as the Dalai Lama's association with India, and as such claims the CTA has no moral legitimacy to govern Tibet. Positions on Tibet after 1950 Tibetan exiles generally say that the number that have died in the Great Leap Forward, violence, or other unnatural causes since 1950 is approximately 1.2 million. However, this number is controversial. According to Patrick French, a supporter of the Tibetan cause who was able to view the data and calculations, the estimate is not reliable because the Tibetans were not able to process the data well enough to produce a credible total, with many persons double or triple counted. There were, however, many casualties, perhaps as many as 400,000. This figure is extrapolated from a calculation Warren W. Smith made from census reports of Tibet which show 200,000 "missing" from Tibet. Even anti-Communist resources such as the Black Book of Communism expresses doubt at the 1.2 million figure, but does note that according to the Chinese census, the total population of ethnic Tibetans in the PRC was 2.8 million in 1953, but only 2.5 million in 1964. It puts forward a figure of 800,000 deaths and alleges that as many as 10% of Tibetans were interned, with few survivors. Chinese demographers have estimated that 90,000 of the 300,000 "missing" Tibetans fled the region. The Central Tibetan Administration also says that millions of Chinese immigrants to the TAR are diluting the Tibetans both culturally and through intermarriage. Exile groups say that despite recent attempts to restore the appearance of original Tibetan culture to attract tourism, the traditional Tibetan way of life is now irrevocably changed. It is also reported that when Hu Yaobang, the general secretary of the Chinese Communist Party, visited Lhasa in 1980, he was unhappy when he found out the region was behind neighbouring provinces. Reforms were instituted , and since then the central government's policy in Tibet has granted most religious freedoms, but monks and nuns were sometimes imprisoned, and many Tibetans (mostly monks and nuns) fled Tibet yearly. The government of the PRC claims that the population of Tibet in 1737 was about 8 million. It claims that due to the 'backward' rule of the local theocracy, there was rapid decrease in the next two hundred years and the population in 1959 was only about one million. Today, the population of Greater Tibet is 7.3 million,
