Astrodatabank is a wiki resource that compiles astrological data, primarily birth details and charts for public figures and significant events. Its origins trace back to 1979 when astrologer Lois Rodden began collecting and publishing this information. Over time, the collection expanded, incorporating data from other collectors like Edwin Charles Steinbrecher and developed by Mark McDonough. The project transitioned ownership multiple times, eventually being acquired by the Swiss company Astrodienst AG in 2008. It was then transformed into a freely accessible wiki project, launched in March 2009, and continues to be maintained and published in English.

The foundation of Astrodatabank was laid in 1979 by astrologer Lois Rodden, who initiated the publication of birth data through her book, 'Profiles of Women.' This endeavor eventually evolved into the creation of Astrodatabank. Mark McDonough played a crucial role in developing the database structure, utilizing over four decades of astrological birth data meticulously gathered by Rodden. Before her passing, Rodden designated Pat Taglilatelo as her successor. The database further expanded by integrating the extensive data collection of Edwin Charles Steinbrecher. In 2005, ownership of the project transferred to Richard Smoot, and subsequently, in 2008, it was acquired by Astrodienst AG, a Swiss company owned by Alois Treindl. This acquisition marked a significant shift, as Astrodatabank was converted into a wiki and made openly accessible.

Astrodatabank has been recognized as a valuable resource for astrological research by various organizations, including the National Council for Geocosmic Research and the Astrological Association of Great Britain. Its collection of verified astrological charts is considered useful for scientific research. Researchers have utilized the data, importing it into statistical software like SPSS for analysis, with some suggesting that Astrodatabank adheres to rigorous astrological methodology and meets social scientific research design standards. The data has also been processed by open-source software like TkAstroDb for statistical analysis, with findings published online. Some research groups have concluded that astrological variations might be explainable by sampling errors rather than inherent astrological influences, suggesting that statistically significant astrological factors are too small for individual prediction.

The data within Astrodatabank is meticulously recorded and rated to ensure reliability. Contributions from editors and data collectors are subject to review by a main editor for notability and accuracy before publication. Entries are ranked using the Lois Rodden Rating system, which mandates full citation of source notes. This system includes categories like 'AA' to differentiate data based on birth certificates from personal memory, and 'DD' for unreliable or dubious information, including contradictory claims. The database continually updates entries to reflect the most current and accurate information available, maintaining a commitment to the integrity of the collected astrological data.
