what percentage of people have a secure attachment style? 25% 40% 50% 75%

Most large studies estimate that around 50–65% of people have a secure attachment style, so among your options, 50% is the best single-choice answer.

Key point

• Reviews of adult attachment research often find that roughly about half or a bit more of the general population is securely attached (commonly cited ranges are 55–65%).

• Self-report surveys in specific countries sometimes land a bit lower (for example, ~38% of Americans in one poll), but these are not considered universal figures.

Why not 25%, 40%, or 75%?

• 25% and 40% are lower than the ranges typically reported in cross-cultural and clinical summaries, which generally show secure attachment as the most common style.

• 75% is higher than most published estimates; even optimistic summaries rarely place secure attachment above the mid‑60% range.

So for a multiple‑choice question, 50% is the closest fit to the research- based range of about 50–65%.
