Yesterday, I looked at the partisanship of early voters. Today, I take a peek of the age and racial demographics of early voters based on data graciously provided by a reader.

The estimates of the racial composition of the electorate are based on estimates of the race of voters with the caveat of the potential for errors. Not everyone named Morales is Latino just as not everyone called Goldberg is Jewish. Nonetheless, the information provide a useful first cut at who is participating in early voting.

Let’s start with the percentage of the electorate in each age group broken down by party:

Early voters skew heavily towards older voters, especially among Republicans. At 74.4%, nearly three-quarters of GOP voters are over age 50. The Democratic share older than 50 is around 5% lower at 69.3%. Among all early voters, which includes unaffiliated and third-party registrants, the share is 68.9%, slightly lower than for Democrats. The low figure reflects much less skew towards older voters among non-major party voters.

In contrast, people 35 and under make up a low share of early voters–11.7% among all voters and just 11.4% among Democrats and 9.5% among Republicans. The latter figure reflects the heavy skew away from Republicans among millennials.

The next table shows the racial composition of each county’s electorate. Percentages add up to less than 100% because the race or ethnicity of many voters is unknown and cannot be reasonably gauged to any extent by proxies. As a result, the percentages presented here are invariably low end estimates.

Among early voters, African Americans are high participants (31%), exceeding their share of the voting-age population. Unsurprisingly, black participants overwhelmingly outnumber other groups in Prince George’s and Baltimore City. In Charles, African-American early voters barely edge out whites–a sign of the continuing evolution of racial demographics in that county.

The encouraging rates of black participation help explain why Democrats are consistently outperforming Republicans in early voting. Not only does Maryland have vastly more Democrats, they are voting at a higher rate than Republicans.

In contrast, Latinos (3%) and Asians (3%) appear to be casting early votes at low rates, reflecting lower rates of citizenship and turnout. Asians compose the highest share of early voters in Montgomery (7%) and Howard (6%). Latinos comprise 6% of early voters in Montgomery, and 3% in Anne Arundel, Frederick and Howard.

In Maryland as a whole, approximately 57% of early voters are white. Again, as the percentages are calculated out of total voters and many could not be placed in any category, the estimates for all racial groups are low.
