Notes:               The U.S. Census Bureau provides annual estimates of income and poverty
                     statistics for all school districts, counties, and states through the
                     Small Area Income and Poverty Estimates
                     (https://www.census.gov/programs-surveys/saipe/about.html) (SAIPE)
                     program. The bureau's main objective with this program is to provide
                     estimates of income and poverty for the administration of federal
                     programs and the allocation of federal funds to local jurisdictions.
                     In addition to these federal programs, state and local programs use
                     the income and poverty estimates for distributing funds and managing
                     programs.
                     
                     Household income includes income of the householder and all other
                     people 15 years and older in the household, whether or not they are
                     related to the householder. Median is the point that divides the
                     household income distributions into two halves: one-half with income
                     above the median and the other with income below the median. The
                     median is based on the income distribution of all households,
                     including those with no income.
                     
                     A confidence interval is a range of values, from the lower bound to
                     the respective upper bound, that describes the uncertainty surrounding
                     an estimate. A confidence interval is also itself an estimate. It is
                     made using a model of how sampling, interviewing, measuring, and
                     modeling contribute to uncertainty about the relation between the true
                     value of the quantity we are estimating and our estimate of that
                     value. The "90%" in the confidence interval listed above represents a
                     level of certainty about our estimate. If we were to repeatedly make
                     new estimates using exactly the same procedure (by drawing a new
                     sample, conducting new interviews, calculating new estimates and new
                     confidence intervals), the confidence intervals would contain the
                     average of all the estimates 90% of the time. For more details about
                     the confidence intervals and their interpretation, see this
