How do you plot a graph from population data?

To plot a graph from population data, first organise the data, then choose the right type of graph.

Start by collecting your population data, which might include years and corresponding population figures. Ensure the data is accurate and complete. Next, decide on the type of graph that best represents your data. For population data over time, a line graph is often the most suitable as it clearly shows trends and changes over periods.

Once you've chosen the type of graph, label your axes. Typically, the x-axis (horizontal) will represent time (years), and the y-axis (vertical) will represent the population. Make sure to use a consistent scale for both axes to ensure your graph is easy to read and interpret.

Plot each data point on the graph by finding the corresponding x and y values and marking them on the graph. For example, if you have data for the year 2000 with a population of 50,000, find 2000 on the x-axis and 50,000 on the y-axis, then place a dot where these two values intersect.

After plotting all your data points, connect them with a line if you're using a line graph. This helps to visualise trends over time. If you're using a bar graph, draw bars up to the correct population value for each year.

Finally, add a title to your graph and label the axes to provide context. This helps anyone looking at your graph to understand what the data represents. For example, you might title your graph "Population Growth from 2000 to 2020".
