How We Determined the Top 200 Jobs of 2010

To quantify the many facets of the 200 jobs included in our report, we determined and reviewed various critical aspects of all of the jobs, categorizing them into five "Core Criteria;" that is, the general categories that are inherent to every job. These are:

Environment, Income, Outlook, Stress and Physical Demands

Below is an explanation of how we determined the rankings in each of these Core Criteria. After each of these Core Criteria were scored and ranked individually, we computed the Overall Rankings, which are explained as the last item in this explanation of the methodology.

1. ENVIRONMENT

Environment Factors

The ranking system used to evaluate a job's environment considers and measures two basic factors of every work environment: the physical and the emotional components. For each occupation, points were assigned for any adverse working condition typically encountered in that job. Thus, the greater number of points a job scores, the worse the rank, while the fewer points awarded, the better the rank.

The following categories and points were used to rate the physical work environment:

Physical Environment FactorsScoring Range
The necessary energy component0-5
Physical demands (crawling, stooping bending, etc.)0-12
Work conditions (toxic fumes, noise, etc.)0-13
Physical environment extremes treated as negative scores0-10
Stamina required0-5
Degree of confinement0-5
Total Maximum Points = 50

 

These categories were used to assess the emotional environment:

Emotional Environment FactorsScoring Range
Degree of competitiveness0-15
Degree of hazards personally faced*0-10
Degree of peril faced by others0-8
Degree of contact with the public0-8
Total Maximum Points = 41

* i.e. co-workers, customers including medical patients, outside stressful situations of all kinds, etc.

Environment Ranking System

The ranking system is designed so that the higher point totals reflect lower quality environments. After the raw scores are added together, they are mathematically adjusted to reflect average work-hours per week. This adjustment provides that jobs which require longer working hours than most have their point total adjusted upward, on a scale that escalates proportionally with the number of hours worked.

The ranking system is designed to give approximately equal weight to the physical factors, with 50 maximum points, and emotional factors, with 41 maximum points. Therefore, jobs that have adverse emotional conditions often as rank as low as those with poor physical conditions. For example, Statisticians' relatively short work week (slightly less than 45 hours), allowed Statisticians to score the least points, 89.520, hence the highest, or number one, rank in the environmental rankings. In comparison, Firefighter, with its very high scoring emotional component and grueling physical factors – including travel, confinement and very long hours – scored more than 3,300 points, the highest score, and therefore the lowest rank in the Environment Rankings.

2. INCOME

The scores shown in the ranking tables might look like average incomes to those familiar with pay levels in the jobs to which they relate. However, the scores are actually a derivative of mid-level incomes, and not the average income at all. Since all incomes shown in this table are estimates rounded to the nearest $1,000, there would be many ties if the mid-level income was the sole basis of the score. Instead, the income score was computed by adding the estimated mid-level income and the income growth potential.

Below is an explanation of growth potential, and how it is computed in the scoring system:

Growth Potential

An Actuary that is starting at a salary of $49,000 could eventually earn $161,000, hence increasing annual income by $112,000, which is 229% higher than the beginning income. Income Growth Potential, therefore, is 229%. Adding this (229) to the mid-level income, which is $85,000, nets a score of 85,229. In the tables a dollar-sign was added showing the score as "$85,229." As you can see, the way this score is expressed very closely resembles an average dollar-denominated income found in an income survey. Therefore, the dollar-sign precedes the score as an accommodation to someone who wishes to get at-a-glance estimates of average incomes.

3. HIRING OUTLOOK

The Three Outlook Factors

The ranking system used to evaluate Outlook awards higher scores to jobs with promising futures. Lower scores indicate a poorer outlook. Our ranking system considers three factors for each occupation. These factors and the weights assigned to them in the ranking system are:

    • Employment Growth:

The "mega factor" for outlook as defined here is expected employment growth through the year 2016, as forecast by the Department of Labor. In the Outlook Rankings this figure is listed in the "Job Growth Through 2016" column. It is expressed as a percentage increase in jobs in a particular career field over a ten year period, 2006-2016, which is the Department's latest available estimate. The Jobs Rated ranking system simply uses this figure as a whole number rather than a percent, and adds and subtracts several numbers to it that are derived from other pieces of data; one is a score for the degree of unemployment and the other is the multiple that one can increase one's salary. Below is more on these additional factors.

    • Income Growth Potential:

This refers to how much a worker can increase his or her income. See the preceding section about income scores and refer to the subsection "Growth Potential" for an explanation as to what this is. This score for Growth potential is then added to the employment growth score.

    • Unemployment:

Unemployment data reflects estimates, mainly from the Department of Labor, for the third quarter, 2009. Below are five ranges of unemployment that were used in the scoring. Because unemployment is obviously a negative thing, a derivative of the unemployment rate of a particular job is subtracted from the sum of Employment Growth and Income Growth Potential.

Below are the ranges, and in parenthesis after each range is the whole number that is subtracted from the sum of the Employment Growth and Income Growth Potential:

Unemployment Data
Very Lowless than 1% - less than 4% (.50)
Low4% - less than 7% (1.00)
Moderate7% - less than 10% (1.50)
High10% - less than 14% (2.00)
Very High14% or higher (2.50)

 

4. PHYSICAL DEMANDS

The Physical Factors

The idea of measuring work has long fascinated physicists. They have even devised formulas for it. The Department of Labor has also developed ways of measuring the physical demands of work and, in part, this was used to formulate these rankings.

One method they use is similar to that used by physicists. It relies on how much weight a person is normally required to lift on the job. Five categories are specified:

Physical Demands Categories
Sedentary WorkRequires the occasional lifting of 10lbs or less
Light WorkRequires lifting a maximum of 20lbs
Medium WorkRequires lifting a maximum of 50lbs, but with frequent lifting of up to 25lbs
Heavy WorkRequires lifting a maximum of 100lbs
Very Heavy WorkRequires lifting in excess of 100lbs, with frequent lifting of 5lbs or more

 

But the federal government also considers other aspects of a job's demands, such as whether the work is primarily indoors or outdoors, and whether or not it involves stooping, kneeling, climbing or balancing. Only when all these factors are considered together can the true physical demands of an occupation be determined.

The ranking system for physical demands used in this report includes many of the elements measured by the Department of Labor. However, an important criterion is added: Overtime – that is, work time in excess of eight hours daily. After all, an executive working till 10 p.m. is likely as tired when he gets home as many construction workers who quit work at 5 p.m.

The Ranking System

In order to compute the Physical Demands of a job, we awarded higher scores to jobs with greater Physical Demands and lower scores to jobs with lesser demands. We arrived at these scores by compiling data used by the U.S. Department of Labor. One point was awarded for each physical component of a job. These components include lifting, pulling, pushing, standing, walking, stooping, kneeling, crawling, climbing, crouching or reaching. We also awarded points for hazards faced, exposure to various kinds of weather, the need for stamina and the work environment.

One to five points was also added for each degree of lifting required based on the five categories previously mentioned, which range from 10 pound lifting at sedentary jobs to 100 pound lifting for very heavy work. One point was also added for each hour, or fraction thereof, that the average worker puts in that exceeds 40 hours per week. These determinations were based on U.S. Census data and sundry estimates provided by those familiar with the work habits of various professionals and tradespeople. The total number of points accumulated represents the score used to determine the rankings.

5. STRESS

The 21 Stress Factors

The amount of stress a worker experiences can be predicted, in part, by looking at the typical demands and crises inherent in his or her job. Our ranking system for stress considered 23 different job demands which can reasonably be expected to evoke stress (see list below). Each demand was assigned a range of points. A high score was awarded if a particular demand was a major part of the job, fewer points were awarded if the demand was a small part of the job, and no points were awarded if that demand was not normally required. For example, "deadlines" was one demand measured. Journalists, who often face daily deadlines, received the maximum of 9 points in this category. In contrast, biologists, who seldom face deadlines, received no points. The demands measured and the point ranges assigned to each area are as follows:

Stress FactorsScoring Range
Quotas0-5
Deadlines0-9
Advocacy0-5
Win or lose situations0-5
Working in the public eye0-5
Competitiveness0-15
Lifting required0-5
Physical demands (stoop, climb, etc.)0-14
Environmental conditions0-13
Machines or tools used0-5
Speed required0-5
Hazards encountered0-5
Own life at risk0-8
Life of another at risk0-10
Precision required0-5
Initiative required0-5
Stamina required0-5
Outdoor work0-5
Confinement0-5
Detail0-5
Meeting the public0-8
Total Maximum Points = 147

 

When computing a score for each occupation, points were added together for all 21 categories. This subtotal was then adjusted to reflect a job's average work hours per week. Jobs exceeding 40 hours a week scored higher final totals, while jobs requiring less than 40 hours scored lower. Calculations involved multiplying subtotal scores by the average weekly work hours and then dividing by 40, the hours in a normal American work week. The calculation is summed up in the following equation:

Stress = Subtotal × Hours 
40

 

To illustrate how this ranking system works, take the case of a firefighter. Firefighters scored maximum and near-maximum points in exertion, physical demands, speed, stamina, working conditions, hazards, outdoor work, risk of a worker's death and death of another. It scored three points in the categories of machines used, meeting the public and instructing. One point was awarded for precision. When the score was adjusted to reflect a firefighter's average long work week of 56.2 hours, the total was 110.936:

 78.958 (subtotal) × 56.2 (hours) = 110.936 (stress score)
40 (average hours)

 

These scores, of course, reflect only a typical stress profile for any given occupation. For any individual worker, stress can vary greatly depending on the particular working conditions, his or her boss and co-workers, mental outlook and a multitude of other factors which play a part in stress.

OVERALL RANKINGS

Overall Rankings refer to the sum of the rankings in each of the above five Core Criteria above. In the Overall Ranking system, it is assumed that each of the five Core Criteria (Environment, Income, Outlook, Physical Demands and Stress) is equally important. Scores are derived by adding together the individual rank that each job has received in those categories. Because a high rank in an individual category means it is more desirable than a low rank, this ranking system translates to the lowest score being the most desirable. Therefore, the lower the score, the higher the Overall Ranking.

For example, the top-ranked job in the Overall Rankings is Actuary. Its Environment rank is 9; Income is 22, and so on. Cumulatively, the ranks of the other three Core Criteria total 46, rendering Actuary with the lowest score, which makes it is the top-ranked job. The lowest ranked job is Roustabout. Its Environment rank is 194; Income is 164 and so on. Cumulatively, the ranks of Roustabout total 928, which is the highest score in the Overall Rankings. This puts Roustabout in the basement, at number 200 out of the 200 jobs.

Methodology for the 2009 Jobs Rated Report


Absurd rating scale

This rating scale is stupid, what about job fulfillment, and since when is physical work a negative? There are far more depressed/suicidal office workers than those in a manual labor job, the human body is meant to be active!
