Shulman divides shoplifters into seven (7) distinct groups, each with certain identifiable characteristics and expected responses if they are caught. The percentage that follows is Shulman's estimate as to the percentage of the total shoplifting population that the particular group comprises.

ADDICTIVE-COMPULSIVE SHOPLIFTERS: 75%
This group emotionally has a lot of repressed anger and often exhibits signs of other compulsive addictions, such as overeating, shopping, drug use, or gambling. These people often give to others and don't take care of themselves. Typically, they will steal items that are often inexpensive, and then give them to others as gifts. If caught, they will show guilt, shame, or remorse. Often, they will breakdown and cry when caught and confronted.

PROFESSIONALS, THOSE WHO STEAL FOR PROFIT OR LIFESTYLE: 5%
Professionals will try to steal high-end, expensive items, often stealing multiple items at one time. Many carry tools and utensils on them to assist with the theft. Most likely, this group will resist arrest if confronted and will attempt to flee the store. If caught and detained, they will remain cool and calm, showing no remorse or emotion.

THE IMPOVERISHED, THOSE WHO STEAL OUT OF ECONOMIC NEED: 5%
Typically, they will steal necessities, like food, diapers, toiletries, or children's clothing. Often, their manner of dress and hygiene may be poor. If caught, they will usually show remorse, but state their frustration with their lack of money, and may voice hostility against a "System" that keeps them impoverished.

THE THRILL SEEKERS, THOSE WHO STEAL ON A DARE OR FOR EXCITEMENT: 5%
These shoplifters will often steal in groups. Many teenagers fall into this category.

DRUG ADDICTS, THOSE WHO STEAL TO PAY FOR A DRUG HABIT: 5%
Like Professionals, they prefer stealing expensive, high end items, usually multiple items at a time. Their appearance often shows signs of substance abuse. They often carry drugs or drug paraphernalia on themselves. They are usually less careful than the Professional, but will likely arrest and flee the store if confronted.

KLEPTOMANIACS ARE THOSE WHO STEAL FOR NO REASON: 1%
Kleptomaniacs are impulsive and often careless. They will often take items they don't need and can't use, like stealing shoes that don't fit. If caught, many will admit they are kleptomaniacs and do not feel much remorse or shame. They will often use common excuses, like "I don't remember taking it", or "I don't know why I took it because I don't even need it".

THE ABSENT MINDED:  1%
People in a hurry, elderly people, people on medications or those who would have cognitive or memory issues.
