🔬Research Data
Marcos Antonio de Lima Filho, PhD.
By sharing this data, I hope to contribute to further studies on innovation and design evolution. Open data fosters an environment of open inquiry, promotes research through the reuse of data, and improves science through verification and replication. The following Github repositories contain the following datasets:
The Evolution of Smartphones and Mobile Handsets, 2000-2020
This dataset is the outcome of my PhD thesis entitled “How Product Designs Evolve”. This study analysed the data sheets of 13,212 mobile phones released globally by 297 brands. This census covered the specifications of feature phones, personal digital assistants (PDAs), and smartphones released between January 2000 and December 2020. Data was collected from specialised mobile phone comparison websites, and 91 product attributes and performance indicators were gathered for each smartphone model.
Dataset:

The Evolution of Commercial Passenger Aircraft, 1932-2020
This dataset is the outcome of my PhD thesis entitled “How Product Designs Evolve”. This census examined the production records and detailed specifications of 283 different aircraft models produced between 1932 and 2020. In this period, 53 distinct manufacturers produced a total of 54,793 airframes, each destined for commercial passenger transportation. This data makes it possible to trace the development of flight technology, from the age of flying boats and piston engines to the emergence of turbojets, turboprops, supersonic airliners, and the modern era of narrow-body and wide-body aircraft. Each aircraft model entry provides detailed specifications across 55 different variables, providing detailed information into model specifications, manufacturer details, role, basic configuration, passenger and cargo capacities, performance metrics, propulsion types, avionics, fuel efficiency, and engine emissions.
Dataset:
Census of Airliner Technology
Purpose:
The Census of Airliner Technology traces the evolution of passenger aircraft technology. It comprises two separate but complementary tables. The first covers the historic production of airframes destined for commercial passenger transportation since 1932. The second covers the model specifications of the airframes produced in the period.
Time Coverage:
1932 - 2020
Statistical Population:
All airliners (commercial passenger aircraft)
Population Size:
54,793 aircraft registries
Manufacturers:
54 manufacturers, from 19 countries/regions, with global reach
Inclusion Criteria:
Airliners with a minimum of 30 passenger seats
Exclusion Criteria:
Airframes registered by government agencies, military, private use, or cargo transportation
Area:
Globally
Types of Data:
Production Lists, Aircraft Specifications (data sheets)
Periodicity:
Annual
