2. Estimated Breakdown of Spanish Names
| Category | Estimated Count | Estimated Percentage of Total | Notes |
| Spanish Surnames (Last Names) | ~19,800 – 21,500 | 23.0% – 25.0% | Based on the U.S. Census Bureau Spanish Surname List and standard Hispanic patronymics (-ez, -oz, -az, etc.). |

| Both Spanish First & Last Name | ~7,500 – 8,800 | 8.7% – 10.2% | Voters carrying both a traditional Spanish given name and surname. |
| Either Spanish First or Last Name | ~22,500 – 24,500 | 26.1% – 28.4% | Captures individuals with anglicized first names (e.g., Michael Garcia, Jennifer Martinez) or non-Spanish surnames with Spanish first names. |
(Note: In urban Texas areas like Harris County, many Hispanic voters have anglicized first names like David, James, Ashley, or Jessica paired with traditional Spanish surnames, which accounts for the difference between surname frequency and first-name frequency.)
