Today, linguistic profiling is based entirely on more efficient and reliable linguistic tools than the ones utilized in as far back as the Old Testament. Now in days, linguistic profilers have been highly dependent on research findings from several specialty areas such as sociolinguistics and psycholinguistics. Specialty areas like these rely on linguistic tools like grammar and semantics, all of which can help professionals uncover answers to how language choices provide details about any individual of interest. Sociolinguistics, in particular, is a field of study where it’s research is put to great use by linguistic profilers due to their primary goal, which is to determine social features that a subject’s language suggests. 
According to Robert Shuy, linguistic profiling has become a useful way to help law enforcement agencies narrow down their lists of subjects. Even though the public often don’t hear about sociolinguistic profilers in action in forensic settings because detectives cannot present their work as evidence to the court system, their discoveries are still very important and worth considering. I believe sociolinguistic features are very important and worth considering because it helps law officials spend their time wisely with the right people (when trying to pinpoint a subject). Sociolinguistic features like age, gender, and _______ help disintegrate a large group of people into a much smaller, therefore, more accurate set of people.
Age plays a role as a factor that influences people’s linguistic choices. Sociolinguists have done research for the past few years in trying to determine the various social variables that contribute to our language. A lot of these studies consist of specialists analyzing speech pertaining to people of different age groups. In the final stages of the studies that involved analyzing children, teenagers and adults’ speech sociolinguists have agreed that speech has age graded features. These age graded features show differences among different age groups terms of pitch, vocabulary, and grammar. Usually, with age, people develop a more sophisticated list of vocabulary words and proper grammatical techniques. Despite having upgrades in one’s language, people sometimes downgrade and use slang words and phrases that one once used as a youngling. 
After reading several linguistic profiling cases, I have noticed that age is a popular language clue because it is probably the most evident of all sociolinguistic features. As shown in The Unabomber Case, the Unabomber mailed packages containing homemade bombs and short notes. The notes and letters the Unabomber had written helped linguistic profiler, Roger Shuy, gather details about the subject. One of the first sociolinguistic features that Shuy gathered was the Unabomber’s potential age interval because the letters contained expressions (i.e., “playing footsie”) that date a writer as having grown up in the 1960s. The writer also frequently used terms like, “other-directed” and made many references to individual “drives,” which suggested his acquaintance with the sociological terms of the sixties (Shuy 8). Clues like these and several others helped the linguistic profiler come to the ultimate conclusion that he believed the Unabomber was around his 50s. Law enforcement officials now had information that narrowed down their lists of potential subjects, putting to show that vocabulary and phrases do indeed help determine a person’s age.
