who has hihgest ppopulation

As of my last update in early 2023, Bangladesh has the highest population among the three countries you've listed. Here's a rough estimate of each country's population at that time:

1. Bangladesh: With a population of more than 160 million people, Bangladesh is one of the most densely populated countries in the world.

2. Vietnam: Vietnam's population is also significant, with around 100 million people.

3. Ethiopia: Ethiopia's population is over 110 million, also very high, but still less than Bangladesh.

Please note that population numbers are constantly changing due to births, deaths, and other demographic factors. For the most current population figures, you should check the latest statistics from a reliable source such as the United Nations or the respective national statistical agencies.
