What is the American Opportunity Index?

The American Opportunity Index measures how well America’s largest companies drive economic mobility and positive career outcomes for their employees—actions that also can help fuel business performance. The Index is the only measure of employer quality to evaluate what really happens to workers at America’s largest employers over time. For more information about the Index, see the About page

How is the Index assembled?

1

We use a range of labor-market data sources to assess the progress of a company’s employees over five years, from 2018 through 2022.

2

We assembled career histories of individual workers based on profiles and resumes they uploaded to career sites such as LinkedIn, analyzed pay data from sites such as Glassdoor, and leveraged job postings data from Lightcast.

3

Unlike most other measures that seek to identify good jobs and places to work, the Index does not rely upon data provided or self-reported by companies. Instead, it is based on objective external sources. Firms cannot choose to opt out of the Index.

Which companies does the Index include?

the Index includes

395

of America’s largest employers

we studied the

500

largest companies headquartered in the United States

we removed

105

firms because we did not have enough data to measure them (102) or those firms went out of business in 2023 (3)

How many workers does the Index assess?

The Index tracks the experience of 5.39 million U.S. workers at the firms we measured.

We focus on jobs open to those without a degree by excluding occupations in which 70 percent or more of workers nationally hold at least a bachelor’s degree.

What does the Index measure?

The Index measures five core elements of corporate performance that we believe are central to effective talent management and drive business growth and opportunity-creation for employees:

metrics
&
Definition
Hiring
How well do companies hire people without degrees and those with little experience?
First Jobs
Percentage of people starting jobs at a company with less than three years of prior experience.
Degree Barriers
Percentage of people starting a job within a given occupation at a company who do not have a bachelor's degree.
Pay
How well do companies pay their employees and increase their compensation over time?
Wage
How well workers in the same occupation are paid at different employers.
Wage Growth
Degree of wage growth for workers who stayed at a given employer for three or more years.
Promotion
How well do companies move people up and prepare them for better jobs elsewhere?
Advancement Within
How likely are workers to be promoted (Promotion Probability), how many further promotions can they expect over time (Continued Promotion), and how large of a raise they can expect at each promotion (Promotion Quality).
Advancement Beyond
How likely workers are to land a higher paying role when they move on to their next employer.
Parity
How well do companies move all people up equally, regardless of race or gender?
Racial Parity
How are a worker’s race, ethnicity, and gender determined?
Race, ethnicity, and gender are determined probabilistically based on a combination of factors, including names, addresses, and educational institutions, using an algorithm originally developed for the Consumer Financial Protection Bureau that was modified by Burning Glass Institute researchers. Because location is a significant factor in the algorithm, career histories were matched with a voter database to determine a likely street address, which is typically missing from online career profiles. For workers who live in states where public voter registration rosters include self-reported race data, we use models based on that information.
Consistency in promotion rates between Black and Hispanic employees and all other employees.
Gender Parity
How are a worker’s race, ethnicity, and gender determined?
Race, ethnicity, and gender are determined probabilistically based on a combination of factors, including names, addresses, and educational institutions, using an algorithm originally developed for the Consumer Financial Protection Bureau that was modified by Burning Glass Institute researchers. Because location is a significant factor in the algorithm, career histories were matched with a voter database to determine a likely street address, which is typically missing from online career profiles. For workers who live in states where public voter registration rosters include self-reported race data, we use models based on that information.
Consistency in promotion rates between male and female employees.
Culture
How well do companies retain their employees and build their careers?
Retention
How long employees stay with an employer.
Leaders From Within
Share of the most highly paid employees who have climbed the ranks internally within the company.

How are companies ranked?

1

For each metric, we start by calculating a score for each of the 12 metrics at each occupation at a company, such as the retention rate for customer service representatives. That allows us to assign a score to every metric by occupation at each company.

2

We then compare that score to the score for that same metric and occupation at other companies—in this case, the retention scores for customer service representatives across all companies.

3

We then weight those scores based on the prevalence of certain occupations at a company, as observed in job postings. If a company has twice as many customer-service representatives as administrative assistants, the customer-service representatives receive greater weighting when calculating a company’s total score for each of the 12 metrics. Each metric accounts for half of its relevant category score.

4

To calculate a company’s overall score, we have weighted the relative importance of each of the five categories based on surveys totaling 1,000 workers at large firms and input from a panel of expert economists. Both the worker survey and expert panel assigned significant priority to metrics of worker mobility and wage. As such, for simplicity, we assign double weighting to pay and promotion, and single weight to hiring, parity and culture.

What might the Index miss?

Online career histories are self-reported, which can yield embellishments and inaccuracies, but our analysis also suggests that those that might occur are shared across firms. There is no reason to believe that Walmart’s employees are any more likely to misrepresent career progress than their counterparts at Target, for instance.

Further, this is a complex exercise involving multiple hard-to-account-for variables. Even the extensive data-driven analysis used to create the Index cannot account for every nuance that shapes real-world worker outcomes and opportunities. Geography may limit workers’ job choices, for example. Very short stints may go underreported on résumés and in online career profiles. Pursuit of additional education or skill development outside of the workplace is not measured here.

On the employer side, companies that rely extensively on contract employees may rank higher than they otherwise might if these contractors were considered employees. We present our methodology with humility, aware of certain limitations yet certain that the core strengths of the analysis will make it useful to business leaders and employees.

What’s new in the 2024 Index?

1

Progress in Company Performance:The American Opportunity Index focuses on relative rankings: Compared to one another, which of the Index’s 395 firms are creating the most opportunity for workers? This year, we wanted to take this a step further and help firms assess how much they were improving year-over-year, on an absolute basis. We focused this analysis on the two measures that drive the greatest long-term opportunity for workers: Promotion and Hiring. On each company page, you’ll find which firms are doing more this year to promote workers and increase workeßr access.

AOI-Glassdoor Sentiment Score: Culture is challenging to measure quantitatively. Our measure of “Culture” in the Index centers around two components: Retention and the share of Leaders at a firm that are drawn from Within. We recognize that only captures some aspects of a firm’s culture – and we wanted to capture it more expansively this year. Therefore, we partnered with Glassdoor to gather Glassdoor reviews for each company in the Index. We then regressed various sub-component scores within each Glassdoor review (Recommend To A Friend, Culture Values, Senior Leadership, Work-Life, and CEO Approval) against the overall score to weight each characteristic according to its correlation with the Overall Glassdoor score to construct our custom Glassdoor Sentiment score. One key insight from this analysis was the CEO Approval emerged as the least weighty metric: it appears that, for Fortune 500 firms at least, a workers’ perception of their CEO is quite unrelated to their sentiment about the firm as a whole.

Updates To Parity: Last year, we ranked firms 1 to 4 on the Parity metric. As we more deeply explored the distinctions in Parity, we learned, thankfully, that there are minimal disparities in Gender and Racial Parity for the vast majority of firms. Therefore this year we are giving firms a 4 on Gender Parity, indicating minimal differences in promotion rates between men and women, or a 1, indicating that material differences still exist. The same methodology is applied to Racial Parity. For firms that score a 1 on Gender Parity and 4 on Racial Parity, or vice versa – we apply a score of 2 on the Category Parity score, which represents the combined Parity scores across Gender and Race.
