Descriptive statistics and regressions of 2D:4D and educational attainment based on RLMS data

We document the descriptive statistics and detailed regression outputs for educational attainment and measured 2D:4D ratios, based on the RLMS data (20th round, conducted in 2011–2012). Regression analysis is conducted using STATA 13, gologit2 which is a special code for the generalized ordered logit regression in STATA environment. We provide graphs of differences in means of 2D:4D ratios by educational attainment. Information about the distribution of self-identified nationalities and fields of university degrees of respondents is presented.

Type of data Individual survey How data was acquired Face-to-face interview conducted by ZAO "Demoscope" Data format SPSS Experimental factors N/A Experimental features N/A Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/dib Measurements were taken by a special team of 2 trained assistants, while other information was taken from the RLMS survey which contains questions regarding an individual's socioeconomic characteristics and family background [1]. The data were anonymized before being provided to the authors for statistical analysis. The finger measurements were taken using electronic calipers. Actual measurements were made from the palmar digital crease to the fingertip of the index and ring fingers. Then measurements were rounded to the nearest millimeter.  Fig. 1. Difference in means of digit ratios by education completed. Females. Note: Significant differences are found for the right hand: D1 (at 5% sig. level), D3 (at 10%).

Note: Significant differences are found for: the right hand D1 (at 1% sig. level), D2 (at 5%); the left hand D1 (at 1%), D2 (at 5%). Note: completed university degree or higher academic degrees refers to the original category "completed higher education and higher levels of education" (the variable "p_diplom", please, consult: https://www.hse.ru/data/2016/06/07/1247611077/R20_ ind_codebook.pdf). Uncompleted secondary school education refers to the category which includes 3 original RLMS categories of educational attainment: 1) 0-6 grades of school; 2) 7-8 grades of school; 3) 7-8 grades of school and some additional education.

I don't necessarily have in mind the nationality that is indicated on your passport."
