Many overweight and obese people die at younger ages, and participants in Flicker's study necessarily had to survive until...

For each, approximately 30,000 households will receive a slightly different questionnaire so that demographers and statisticians can use data - along with follow-up interviews - to decide if the modification helps or hurts the accuracy and consistency of information collected. "We hope this will help us better understand the way people identify with these concepts," says Nicholas Jones, chief of the Census' racial-statistics branch. One change being tested: deleting the word Negro...
