Land er ikke altid synonymt med stat, da et land kan indgå i en større statsdannelse, som f.eks. Grønland og Færøerne, der sammen med det egentlige Danmark indgår i den danske stat. Ligeledes er land ikke altid synonymt med nation, da indbyggerne i et land ikke nødvendigvis deler en fælles national identitet.
