Data Processing Pipeline

Note: Since all preprocessed data files are provided, you can skip directly to the Analysis section (Section 2) if you want to replicate the results without re-running the preprocessing steps. Please refer to data_documentation.md for details on the different data used.

Run the following scripts in order from the code/ directory:

1. Data Preprocessing

1. preprocess_iso_codes.py

   • Processes ISO country codes
   • Creates standardized country code mappings

2. preprocess_population.py

   • Processes country-level population data
   • Processes US state-level population data
   • Outputs working age population statistics

3. preprocess_gdp.py

   • Downloads and processes IMF country GDP data
   • Processes BEA US state GDP data
   • Creates standardized GDP datasets

4. preprocess_onet.py

   • Processes O*NET occupation and task data
   • Creates SOC occupation mappings

5. aei_report_v3_preprocessing_1p_api.ipynb

   • Jupyter notebook for preprocessing API and Claude.ai usage data
   • Prepares data for analysis

2. Analysis

Analysis Scripts

1. aei_report_v3_change_over_time_claude_ai.py

   • Analyzes automation trends across report versions (V1, V2, V3)
   • Generates comparison figures showing evolution of automation estimates

2. aei_report_v3_analysis_claude_ai.ipynb

   • Analysis notebook for Claude.ai usage patterns
   • Generates figures specific to Claude.ai usage
   • Uses functions from aei_analysis_functions_claude_ai.py

3. aei_report_v3_analysis_1p_api.ipynb

   • Main analysis notebook for API usage patterns
   • Generates figures for occupational usage, collaboration patterns, and regression analyses
   • Uses functions from aei_analysis_functions_1p_api.py

Supporting Function Files

• aei_analysis_functions_claude_ai.py

  • Core analysis functions for Claude.ai data
  • Platform-specific analysis and visualization functions

• aei_analysis_functions_1p_api.py

  • Core analysis functions for API data
  • Includes regression models, plotting functions, and data transformations
