Shanecia is of African-American origin, derived from the Swahili word "shanana," meaning to grow tall and strong. It gained popularity in the United States during the 1970s and 1980s, often used as a unique alternative to more traditional names like Shanice or Shaniqa. The name has also been associated with notable figures such as Shanecia Knowles, a member of the American R&B group Destiny's Child.
"Shanecia's popularity peaked in the early 90s with a high of 12 births in 1992. Since then, its prevalence has steadily decreased, with fewer than 10 births annually from 1994 onwards."
