I think the statistics are likely incomplete and flawed. At
low speeds and for small people, airbags are often more dangerous than the collision that triggered them. Especially the frontal ones that blow up in your face. Broken noses, black eyes, bruises, lacerations.
Financially airbag deployment tends to total many older or less valuable vehicles even if the rest of the vehicle is sound.
Wearing your seatbelt is the best protection. Seatbelt plus airbag is a bit safer for more serious collisions. Airbags without seatbelts is less safe than no airbags are all. I'm all for seatbelts, less for the big frontal airbags.
