This scenario assumes no population change due to migration and only reflects change due to natural increase (births and deaths). The 0.0 scenario is useful as a baseline comparison and is NOT typically used in real-world applications. For more information, please refer to the Population Projections Methodology or contact our office.

This scenario assumes population change due to migration at a rate of 1/2 of the 2000-2010 migration rate and also reflects changes due to natural increase (births and deaths). The 0.5 scenario is typically used for long range projections depending on the characteristics of the area being reviewed. For more information, please refer to the Population Projections Methodology or contact our office.

This scenario assumes population change due to migration at a rate equal to the 2000-2010 migration rate and also reflects changes due to natural increase (births and deaths). The 1.0 scenario is typically used for short range projections depending on the characteristics of the area being reviewed.
