III-08e: Median Earnings of Humanities Majors as a Share of Median Earnings of Majors in Other Selected Fields, by Age, 2018 (Terminal Bachelor’s Degree Holders)*

* For workers employed 35 or more hours per week for 50 or more weeks in the previous 12 months. For an inventory of the particular degree programs included under each of the broad academic fields to which the graph refers, see the ACS-HI Crosswalk.

Source: U.S. Census Bureau, 2018 American Community Survey Public-Use Microdata Sample. Data analyzed and presented by the American Academy of Arts and Sciences’ Humanities Indicators (www.humanitiesindicators.org).

The information presented here is based on an original analysis by the Humanities Indicators (HI) of data from the American Community Survey (ACS), which has been administered on an annual basis by the U.S. Census Bureau since 2005. The ACS replaced the “long form” version of the decennial census and collects information—used to allocate billions in state and federal funding—about Americans’ personal characteristics, family composition, employment, income, and housing.

For the purposes of ACS, the U.S. Census Bureau defines earnings as “the sum of wage or salary income and net income from self-employment. ‘Earnings’ represent the amount of income received regularly for people 16 years old and over before deductions for personal income taxes, Social Security, bond purchases, union dues, Medicare deductions, etc. An individual with earnings is one who has either wage/salary income or self-employment income, or both. Respondents who ‘break even’ in self-employment income and therefore have zero self-employment earnings also are considered ‘individuals with earnings’” (from ACS documentation provided at http://www2.census.gov/programs-surveys/acs/tech_docs/subject_definitions/2014_ACSSubjectDefinitions.pdf, p. 83).

The age ranges selected for the two types of degree holder with which these indicators deal—those with a terminal bachelor’s degree and those who went on to earn an advanced degree—reflect the additional time required to pursue an advanced degree, the age at which earnings peak for each group, and the need for enough survey responses to ensure the reliability of the earnings estimates. 

Quartiles are statistics that divide the observations of a numeric sample into four groups, each of which contains 25% of the data. The lower, middle, and upper quartiles are computed by ordering the values for a particular variable from smallest to largest and then finding the values below which fall 25%, 50%, and 75% of the data. The middle quartile is called the median.

The ACS permits respondents to specify up to two fields of bachelor’s degree. For the purposes of this analysis, an individual was counted as having a bachelor’s degree in the humanities if the field of either reported degree was within the scope of the humanities as specified by the HI. Information regarding the specific disciplines treated as within the humanities for the purposes of this analysis is provided in the ACS-HI Crosswalk.

The ACS does not ask respondents about their amount of work experience. The Humanities Indicators (HI) thus uses age to distinguish between workers who are in the first years of their career and those who are more experienced. Age and work experience are not perfectly correlated, but age does provide an approximate measure of work experience that allows the HI to examine the effect of this experience on unemployment and earnings of humanities majors.
