Step 1: Define sex ratio. It is the ratio of females to males in a population, often expressed as the number of females per 1000 males. A ratio above 1000 indicates more females than males.
Step 2: Analyze the demographics of the given countries. Many Eastern European countries, including Latvia, have significantly more women than men. This is often attributed to a legacy of high male mortality rates in the 20th century. In contrast, Qatar has the world's lowest sex ratio due to its large population of male migrant workers.
Step 3: Conclude based on data. Latvia consistently ranks among the countries with the highest sex ratio globally.
