The estimate for one voter is a set of probabilities, never a fact about that person.",
      "Counts are expected values: the sum of the probabilities for each group, rounded. They describe groups of voters and are most reliable for large groups. A cell of 1 to 9 is hidden like any other.",
      "BISG is known to err in a pattern. In integrated areas it tends to place Black voters in the white group, and it identifies multiracial voters, Native Americans and Pacific Islanders poorly: all of them land in 'other' or in another group. Hispanic and Asian estimates rest heavily on surname.",
      "ZIP code is coarser than a census block, so the geographic part of the estimate is weaker than in studies that geocode addresses. Voters with no usable ZIP code are placed using their county.",
      "The estimate does not use party, age or sex, so the race by party and race by age tables do not repeat what the model was given. Active and inactive registrants are both counted.",
      "The comparison with the Census is rough: it sets the estimated race of registered voters against the 2020 voting-age population, and registration rates differ by group."

    "Participation figures describe the people on the voter list today, not the electorate on election day. Voters who have since moved, died or been removed are missing from the file, both as voters and as registered voters. Past elections are therefore undercounted, the older the election the more is missing, and these are not official turnout figures. The State Board of Elections publishes official turnout for each election.",
    "A voter counts as eligible for an election if they were registered by election day and turned 18 by it (by that year's general election, for a primary), or if the file records a vote for it. Age bands use age today.",
    "Party switching, removals, and net registration change cannot be measured from a single snapshot. They need two snapshots compared voter by voter.",
    "The file records whether someone voted, not how (early, mail, or election day).",
    "Cells with 1 to 9 voters are hidden. Hidden cells are not rebalanced, so rows may not sum to their totals.",
    "Active counts in the file are about 1% below the State Board's monthly registration report for the same month. The monthly report remains the official count; shares and participation rates here are computed within the file.",
    "Registration cohorts show survivors: current voters by the year they first registered in Maryland, not everyone who ever registered.",
    "New registrants are voters whose county and state registration dates match, which marks a first registration in Maryland, and who were 18 or older when they registered. Voters who pre-registered at 16 or 17 are left out, because the youngest of them are not yet in the file. Party is the voter's party today, not the party they chose when they registered."
