Organizing and analyzing the community mortality rates for six large states in the USA recorded between around 1958 to 1995.
This section currently comprises the Ph.D. Thesis of Dr. Janice A. Vatland in which she tested and found valid the null hypothesis that the distribution of cancer death rates among large and small communities in Pennsylvania, Massachusetts, New York, California, Texas and Florida was no greater than expected by chance. As her work comprised data for the 21 most frequent forms of late-onset cancer deaths (65-84 yrs) and six most frequent forms of pediatric cancer deaths (0-19 yrs.),
These clear and convincing findings led us to curtail studies of U.S. communities aiming at discovering communities at elevated environmental risk as the Vatland Thesis demonstrated that there was no support for the hypothesis that late 20th century cancer risk was stratified among communities of high or low risk.
