1. The problem is about rounding populations to the nearest 1000 and finding the maximum possible population for Birmingham. 2. The population rounded to the nearest 1000 is 1,020,000. 3. When rounding to the nearest 1000, numbers from 1,019,500 up to 1,020,499 round to 1,020,000. 4. To find the maximum number that rounds to 1,020,000, we find the highest number that rounds down to it, which is 1,020,499. 5. Check the given options: 1,019,500 rounds to 1,020,000 but is the minimum rounding value. 6. 1,020,049 and 1,020,499 are within the rounding range. 7. 1,020,500 rounds to 1,021,000 and thus is too high. 8. Therefore, the maximum number of people who live in Birmingham, rounding to 1,020,000, is 1,020,499. Final answer: 1020499
