Answer 1

Answer:

Linguistic diversity index (LDI) may refer to either Greenberg's (language) Diversity Index[1] or the related Index of Linguistic Diversity (ILD) from Terralingua, which measures changes in the underlying LDI over time.[2]

Greenberg's Diversity Index (LDI) is the probability that two people selected from the population at random will have different mother tongues; it therefore ranges from 0 (everyone has the same mother tongue) to 1 (no two people have the same mother tongue).[3] The ILD measures how the LDI has changed over time; a global ILD of 0.8 indicates a 20% loss of diversity since 1970, but ratios above 1 are possible, and have appeared in regional indexes.[4]
