Institute for Economics & Peace (IEP) menghasilkan Global Peace Index (GPI), mengukur peacefulness relatif negara dan kawasan. GPI memeringkat 163 negara bagian dan teritori (secara kolektif berjumlah 99,7 persen dari populasi dunia). Dalam dekade terakhir, GPI telah menghadirkan tren meningkatnya kekerasan global dan berkurangnya kedamaian. Indeks pertama kali diluncurkan pada Mei 2009, laporan berikutnya dirilis setiap tahun.

Sepuluh indikator secara luas menilai apa yang dapat digambarkan sebagai keselamatan dan keamanan di masyarakat.
