Highlight ten factors that can affect tourism demand and I will develop them myself.

Here are ten factors that may affect tourism and brief descriptions of each.

1. Weather- A tourist's preference for weather is a big factor in their decision to visit somewhere. If a person really enjoys warm weather, they are not likely to go somewhere cold unless there are more important factors influencing their decision.

2. Natural disasters- This is somewhat related to weather, but far more dependent upon geographic features and geothermal processes. The risk of earthquakes, tsunamis, floods, and volcanoes may deter a tourist from visiting a particular location. 

3. Cost- A visit to another city, state, or country can potentially be quite expensive. A person's economic status influences their decision on where to visit based on how big of an impact a trip would have on their finances.

4. Health- People may be nervous about the idea of travelling to a place where the health status and lifestyle are very different from what they are used to. Alternately, people may choose to travel to a particular place for the health benefits they believe that location offers.

5. Language spoken- Some people feel that inability to speak the local language would be a problem in visiting a new place. To overcome this, they may study the language, hire an interpreter or tour guide, or not travel at all.

6. Availability of certain services- Before travelling, many people look into whether or not they can use their mobile phones on their trip. They may also consider emergency scenarios and whether or not there are hospitals, police, or fire-fighting services in the area.

7. Religion- For many people, religious life is a big factor in their decision to travel. Visiting sites where great religious figures once lived, worked, or built can be a powerful spiritual experience.

8. Cultural attitudes- Depending on the attitudes of one culture towards another, someone may decide that certain places are especially "good" or "bad" to visit.

9. Leisure activities- A person may choose to travel to a particular place for leisure activities they have never tried before, or because this location offers especially good opportunities for the activity. Many people like to travel to warm beaches or the mountains for the particular leisure activities which can only be done there. 

10. Conflict- This is related to cultural attitudes but has much more to do with interaction between individuals and groups of people. If a nation is actively engaged in conflict situations or is at threat of conflict, people are less likely to visit as tourists.
