Linguistic diversity index (LDI) or Greenberg’s diversity index is an index to measure how diverse a country’s languages are. It is on a scale of 1 to 0 with 1 indicating total diversity (that is, no two people have the same mother tongue) 0 indicates no diversity at all (that is, everyone has the same mother tongue).[1] The computation of the diversity index is based on the population of each language as a proportion of the total population. The index cannot fully account for the vitality of languages. Also, The distinction between a language and a dialect is fluid and often political. A great number of languages are considered to be dialects of another language by some experts and separate languages by others.
