Abstract
This survey serves as the tenth in a series of toxicology salary surveys conducted at 3-year intervals and beginning in 1988. An electronic survey instrument was distributed to members of the Society of Toxicology, American College of Toxicology, and 8 additional professional organizations. Question items inquired about gender, age, degree, years of experience, certifications held, areas of specialization, society membership, employment and income. Overall, 1338 responses were received. The results of the toxicology salary survey provide insight into the job market and career path for current and future toxicologists.
Keywords
This is the 10th in a series of salary surveys conducted at 3-year intervals for toxicologists that began in 1988. Previous salary surveys were conducted in 1988, 1 1991, 2 1995, 3 1998, 4 2001, 5 2004, 6 2007 (which was posted electronically but not published), 2012, 7 and 2016. 8 In addition to presenting the 2020 results, herein we are providing additional data and an analysis of the trends for employment and pay in toxicology over the last 30 years.
The 10th Triennial Toxicology Salary Survey was conducted as a joint project by the American College of Toxicology and the Society of Toxicology (SOT). In addition to the 2 parent organizations, 8 others (the Teratology Society, the Society of Toxicologic Pathology, the Safety Pharmacology Society, the American Board of Toxicology, the Academy of Toxicological Sciences, the Roundtable of Toxicology Consultants, the Society of Environmental Toxicology and Chemistry, and the Environmental Mutagenesis and Genomics Society) supported the effort by distributing the Survey Monkey-based instrument to their memberships.
Survey instruments were distributed electronically, with responses going to Survey Monkey. A total of 1,338 responses were received, up slightly from the 1,293 responses received for the previous survey. Figure 1 provides a summary of the number of doctoral respondents across the 30 years of surveys.

The demographics of responses are summarized in Tables 1A through 1H and include respondents’ gender, age, degree, years of experience, certifications held, and areas of specialization. The survey instrument was similar to the form of the 2016 survey, developed in conjunction with the SOT Career Resource and Development services, which included questions evaluating periods of unemployment. It should be noted that there continues to be a significant increase in the number of individuals reporting 6-figure incomes and in those receiving significant sums as bonuses, as is reflected particularly in Tables 2 and 3. In addition, about 25% of respondents received additional professional income outside their primary employer, as shown in Table 4. The survey methodology employed conformed to standard procedures, 9 though the response rate for this survey remains high for such endeavors.

Salary estimates for purposes of calculation were taken to be the midpoint of the range, for example, for the salary range of US$90,000 to US$99,999, a mean value of US$95,000 was used in all calculations. In addition, there was a significant number of incomplete responses that required further estimation by statistical methods. The incomplete responses and the methods used to handle them were: Nineteen respondents did not indicate a gender. These results were not included in the breakdowns. Fourteen respondents indicated a salary >US$250,000 without writing the actual amount in the area provided. The salary used for calculation was US$250,000. This probably led to a bias toward lower average values. Fifty-three respondents indicated they received bonuses, commission, stock options, or profit sharing without indicating the amount. These were excluded from consideration.
A total of 1,021 of the respondents (588 men and 433 women) were full-time employed holders of doctoral degrees in the United States. Table 5 presents the mean salaries (± 1 standard deviation [SD]) for these individuals, sorted by years of experience after receipt of their degrees, gender, and field of employment. Salaries are in thousands of US dollars per year, with necessary conversions having been made for other currencies. Figure 2 provides an across-survey analysis of doctoral salaries for respondents with 1 to 3 years of experience postterminal degree.

Discussion and Conclusions
The current survey results point to a number of different trends that deserve attention by major professional societies and add some insights into the job market, career path, and the conduct of future toxicology salary surveys. First, although the situation continues to improve for most entry-level and early career positions, women continue to be compensated at a lower level than their male counterparts. Second, salaries as a whole have increased in the field, but the most impressive differences are not by geographic location of place of employment but rather by type of employer. Additionally, certification continues to play a significant positive role in compensation. Periods of unemployment remained low in 2017, with most unemployment lasting 6 months or less. Most employers (over 91%) provided health insurance and retirement plans for employees.
Finally, the lag between survey responses being provided by participants, the availability of data for analysis, and the publication of these data were excessive. Furthermore, the inclusion of those who were not holders of doctorates was insufficient. The data collection for the next survey should be revised to improve the coverage of potential respondents as well as decrease the timing from survey distribution to publication.
