What people say in everyday speech
〜以上/〜も
"〜からいる/からある" is a written expression, common in news reports and formal explanations, for stressing that a number is far greater than expected. In everyday speech the more direct "〜以上" is used, or the particle "〜も" is simply added for emphasis, as in "3000人以上の観客" and "10kgもあるかばん". "からいる/からある" carries a slightly formal, emphatic nuance, so friends chatting wouldn't go out of their way to say it.
Used to mean "to have a major impact on ~," as in 「命にかかわるけが」 (an injury that threatens one's life). It is also used to mean "to be related to ~," as in 「教育にかかわる仕事」 (work related to education).
