how has the world populatation changed over the last 200 years?

The death rate has gone down and the birth rate has gone up.

To understand how the world population has changed over the last 200 years, we can analyze historical data on birth rates, death rates, and overall population growth. Here's a step-by-step explanation of how you can find this information:

1. Data Sources: Look for reliable sources that provide data on world population over time. Some reputable sources include the United Nations, World Bank, and the U.S. Census Bureau. These organizations collect and analyze demographic data from various countries and regions.

2. Population Data: Access the historical population data from these sources. You can typically find this information in the form of tables, charts, or reports. Ensure that the data includes a wide range of years, preferably covering the last two centuries.

3. Birth Rate: Analyze the birth rate trends over time. The birth rate is the number of live births per 1,000 individuals in a population. Look for patterns or changes in birth rates over different time periods, paying attention to any significant increases or decreases.

4. Death Rate: Examine the death rate trends over time. The death rate represents the number of deaths per 1,000 individuals in a population. Compare the changes in death rates with birth rates to understand the overall impact on population growth.

5. Population Growth: Calculate the overall population growth rate. This can be done by subtracting the death rate from the birth rate, considering other factors such as migration. Analyze how population growth rates have varied over time, as this will provide insights into global population changes.

6. Long-Term Analysis: Evaluate the data over the entire two-century period. Look for any significant shifts or trends in population growth, such as periods of rapid growth or deceleration. Consider other factors that may have influenced population changes, like advancements in healthcare, technology, and agricultural practices.

Remember, world population trends are complex and influenced by various factors. The analysis of historical data from reliable sources will help you understand how birth rates, death rates, and population growth have changed over the last 200 years.
