  "definition": "1. A subset of the target population that has been identified for a specific purpose, usually requires the ability to estimate an attribute of the subpopulation (i.e., a fish IBI for all lotic streams with a Strahler order of < 4).\n\n2. Any subset of a population, usually having a specific attribute that distinguishes its members from the rest of the population, for example, lakes from a specified population that are above 1000 m in elevation. Subpopulations are important entities in the EMAP plan. Any defined subpopulation is subject to characterization via estimation of subpopulation attributes and comparison to other subpopulations. It is this focus that imposes the greatest restrictions on the EMAP design and establishes the primary directions of the EMAP analyses.\n\n3. A subset of the target population that has been identified for a specific purpose, usually requires the ability to estimate an attribute of the subpopulation.\n\n4. Subset of the target population that has been identified for a specific purpose, usually requires the ability to estimate an attribute of the subpopulation (i.e., a fish IBI for all lotic streams with a Strahler order of < 4).",
