The choice of parliamentary structure does not depend on the size of the population: China (population 1.3 billion) has a unicameral parliament while the parliament of Saint Lucia (population 170,000) is bicameral. Instead, the structure is the result of the specific history, context and parliamentary tradition of each country. Some parliaments choose to change their structure, as in Tunisia where a second chamber (the Chamber of Councillors) was created in 2005.
