Every five years, the American Chemical Society surveys its domestic members who are under 70 years old (and not student-, retired-, or emeritus-status members) to learn about salary and employment trends in chemical and allied occupations and professions. The survey, known as the ChemCensus, is part of ACS’s salary and employment survey legacy, which has been performed annually for more than three decades. These surveys are solicited under the authority of the ACS Committee on Economic and Professional Affairs Subcommittee on Surveys. The 2010 ChemCensus reached approximately 87,000 members via email and mail. Participation is voluntary. Respondent identities will remain strictly confidential and all information will be analyzed in aggregate. Data generated by the ChemCensus and the annual salary and employment surveys will inform articles for C&EN magazine, topical research briefs, the Salary Comparator, and the Employment Dashboard.
