A geographer may decide to use a proportional symbol map over a dot density map for several reasons, including:
1. Clarity: A proportional symbol map allows for clear visualization of the magnitude or intensity of a particular phenomenon or variable at different locations. By using varying symbol sizes, the map effectively represents the relative values of the data, making it easier to interpret.
2. Generalization: Proportional symbol maps provide a more generalized representation of data. The size of the symbols can be adjusted to show a range of values, making it easier to identify patterns and trends across larger regions. This is particularly useful when dealing with large datasets or when a more general overview of the distribution is required.
3. Ease of interpretation: Proportional symbol maps are often more intuitive and easier to interpret for non-experts or a wider audience. By representing values through symbol size, it becomes easier to understand the spatial distribution of the variable being depicted on the map.
4. Flexibility: Proportional symbol maps offer flexibility in symbol design. Depending on the specific needs of the data and the research question, the symbols can be varied in shape, color, or other visual attributes, allowing for additional information to be represented alongside the size of the symbol.
5. Limitations of dot density maps: While dot density maps can be useful for showing the density or concentration of a phenomenon, they can become visually cluttered and difficult to interpret when dealing with larger datasets or areas with high population densities. Proportional symbol maps can provide a clearer representation in such cases.
Overall, the choice between a proportional symbol map and a dot density map depends on the specific research question, dataset, and desired level of detail and generalization.

Responses
A proportional symbol map would be better if the subject being studied had discrete units which could be represented individually.
A proportional symbol map would be better if the information being represented was quantitative data in the form of percentages.
A proportional symbol map would be better if the subject being studied had varying sizes and intensities.
A proportional symbol map would be better if the information being represented stayed consistent across similar locations and changed gradually over different distances.

All of the provided responses are valid reasons why a geographer may decide to use a proportional symbol map over a dot density map. Each reason highlights a specific advantage of using a proportional symbol map in certain situations. Here is a breakdown of each response:
- A proportional symbol map would be better if the subject being studied had discrete units which could be represented individually: This suggests that a proportional symbol map is more suitable when representing discrete entities, such as individual points of interest or discrete units of a certain phenomenon. Each symbol can represent one unit, allowing for clear visualization and analysis.
- A proportional symbol map would be better if the information being represented was quantitative data in the form of percentages: This indicates that proportional symbol maps are effective in visually representing quantitative data in the form of percentages. The size of the symbol can be proportionally adjusted based on the percentage value, providing a clear visual representation of the data.
- A proportional symbol map would be better if the subject being studied had varying sizes and intensities: This reason suggests that a proportional symbol map is more suitable when studying a subject that exhibits variations in size or intensity. The size of the symbol can be used to represent these variations, allowing for a more accurate representation of the subject's characteristics or attributes.
- A proportional symbol map would be better if the information being represented stayed consistent across similar locations and changed gradually over different distances: This implies that a proportional symbol map is more appropriate when the data being represented has a consistent pattern across similar locations and changes gradually over different distances. Proportional symbols can effectively convey this gradual change and pattern, providing a clear visualization of the data.
- A proportional symbol map would be better if the subject being studied had discrete units which could be represented individually: This suggests that a proportional symbol map is more suitable when representing discrete entities, such as individual points of interest or discrete units of a certain phenomenon. Each symbol can represent one unit, allowing for clear visualization and analysis.
