To quantify the many facets of the 200 jobs included in our report, we determined and reviewed a wide range of critical aspects and categorized them into four "Core Criteria" -- that is, the general categories that are inherent to every job. These are environment, income, outlook and stress.
Each of those core categories includes a range of sub-categories that are related to the core. For instance, this year for the first time physical demand was integrated into the environment scores rather than measured as a separate core (see below for more details).
Much of the data used to evaluate each job comes from the U.S. Department of Labor and the Bureau of Labor Statistics (BLS), as well as from a range of other governmental agencies, trade associations and private survey firms.
Jobs Rated calculates the Environment score for each job by measuring two basic factors common to every work environment: the physical and the emotional components.

Points are assigned for every adverse working condition typically encountered, so the greater number of points that a job scores, the worse the rank. Conversely, the fewer points a job gets, the better it ranks. The following categories and points are used to rate the work environment:
|EMOTIONAL FACTORS||Scoring Range|
|Degree of competitiveness||0-15|
|Degree of hazards personally faced||0-10|
|Degree of peril faced by others working alongside||0-8|
|Degree of the public contact||0-8|
|TOTAL MAXIMUM POINTS = 41|
|PHYSICAL FACTORS||Scoring Range|
|Necessary energy component||0-5|
|Physical demands (crawling, stooping bending, etc.)||0-12|
|Work conditions (toxic fumes, noise, etc.)||0-13|
|Degree of confinement||0-5|
|TOTAL MAXIMUM POINTS = 40|
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 Department of Labor (DOL).
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 the elements, stamina required and the workplace atmosphere.
One-to-five points were also added for each degree of lifting required based on the five categories previously mentioned, ranging 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 on the job.
These determinations were based on U.S. Census data and estimates provided by groups related to the industries being scored. The total points accumulated represent the score used to determine the rankings.
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:
An actuary at a starting salary of $54,000 (“beginning income”) could eventually earn $168,000 (the “advanced level”), hence increasing annual income by $114,000, a 211% increase from the beginning income. Income Growth Potential, therefore, is 211%. Adding this (211) to the “mid-level income” of $91,000 nets a score of 91,211.
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.
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:
1. Employment Growth:
The "mega factor" for outlook as defined here is expected employment growth through the year 2020, as forecasted by the Department of Labor. It is expressed as a percentage increase in jobs in a particular career field during the period, 2010-2020, 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 tied to one's ability to increase one’s salary. Below is more information on these additional factors.
2. 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 data reflects estimates, mainly from the Department of Labor, for the the latest available measurement period. Below are five ranges of unemployment that were used in the scoring. Because unemployment is obviously a negative attribute, 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 unemployment rankings. Listed after each range in parenthesis is the range of numbers that is subtracted from the sum of the Employment Growth and Income Growth Potential, depending on the degree of unemployment within each designation, which is shown at the far left of the table.
The 11 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 considers 11 different job demands which can reasonably be expected to evoke stress (see list below). Each demand is assigned a range of points. A high score is awarded if a particular demand is a major part of the job, fewer points are awarded if the demand is a small part of the job, and no points are awarded if that demand is not normally required. For example, "deadlines" was one demand measured. Newspaper reporters, who typically 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 FACTORS||Scoring Range|
|Travel, amount of||0-10|
|Growth Potential||(income divided by 100)|
|Working in the public-eye||0-5|
|Physical demands (stoop, climb, etc.)||0-14|
|Own life at risk||0-8|
|Meeting the public||0-8|
|Life of another at risk||0-10|
To compute a score for each occupation, points are added together for all 11 categories.
However, note that these scores 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.
5. OVERALL RANKINGS
Overall Rankings refer to the sum of the rankings in each of the above five Core Criteria. However, they are not equally weighted. In the Overall Ranking system, one third of the score is based on Income rank, one third on Outlook rank and one third on “Preferential Factors,” which are the rankings in Environment/Physical Demands and Stress, each one of these being weighted equally, though their sum is weighted as one-third of the Overall score. You can also think of them as “comfort levels” pertaining to the workplace environment, the physical demands and the stress factors that we’ll accept if the money and long-term security is good.
The logic, simply put, is that most of us work mainly to earn a living and the most important criteria are therefore Income and Outlook, the latter being of course related to employment and income security over the long haul. If we can work at a job that has a high income and a good lookout, we will accept lots of things that go with these jobs, e.g. Stress, Physical Demands and the Environment, be it good or bad, in our opinion.
After the weights of these five Core Criteria are adjusted, they are added to derive the Overall Score. 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.
