Greetings, I have two following topics: 1- The relationship between technological progress and economic growth OR 2- Study of the road accidents in the rural areas of the city

Could someone please help me to: 1- Find what kind of dataset I can use for statistics for ONE of two topics 2- Describe the single variables in the dataset to determine which variables are relevant to the topic (Distributions, PMFs, CDFs). 3- Identify relationships between some variables

Feel free to take any topic that you are comfortable with.

Thank you so much in advance
