Sociologists classify populations into groups using seven main factors: socio-professional category, income, education level, gender, position in the life cycle (age), place of residence, and household composition. These factors must both structure (create groups) and hierarchize (rank groups by advantage) society to be considered valid for analysis.
Socio-professional categories (PCS) are a key factor, structuring individuals into groups like executives, intermediate professions, workers, employees, farmers, and artisans/merchants. These groups are hierarchized, with executives typically being the most advantaged (higher income, longer life expectancy) and workers/employees often the most disadvantaged.
Income significantly structures society, allowing classification into income deciles (e.g., the poorest 10%, the richest 10%). It also hierarchizes, as higher income groups enjoy more advantages, including higher life expectancy (a 10-year difference between the richest and poorest 10%), greater wealth, homeownership, and political influence.
Education level is another important factor, structuring individuals into groups based on their highest degree (e.g., no diploma, vocational training, Bachelor's, Master's). It also hierarchizes, with higher educated individuals typically having better incomes and lower unemployment rates.
Gender is a structuring factor, creating groups of men and women. It also hierarchizes society, with men historically holding more advantages (higher incomes, greater political representation). Age, or 'position in the life cycle,' is also a structuring factor, creating age-based groups (e.g., 20-somethings, 40-somethings). These groups are often hierarchized, with those in their 40s generally more advantaged than those in their 20s (lower unemployment, higher income, homeownership).
Place of residence structures society into groups like urban, suburban, and rural dwellers. It also hierarchizes, as urban residents often have better access to public services, transportation, and stable incomes. Household composition structures society based on the number of adults and children. It hierarchizes, with single-parent families being the most disadvantaged; in France, 40% of single-parent families live below the poverty line.
The socio-professional structure represents the proportion of each PCS in total employment. Since 1950, this structure has undergone four major transformations: salarization (increase in salaried jobs), tertiarization (increase in service sector jobs), increased qualifications, and feminization of employment.
Salarization is the process of increasing salaried employment and decreasing non-salaried employment. This trend, driven by the growth of large companies (e.g., IKEA replacing artisans, supermarkets replacing small shops) and consolidation in agriculture, transformed independent workers into employees.
Tertiarization refers to the growth of the service sector. This is due to two main factors: increased household incomes after WWII, leading to greater demand for non-essential services (travel, leisure, dining), and the delocalization of manufacturing plants, which shifted industrial jobs abroad while new service jobs were created in France.
Since the 1950s, the duration of schooling has increased significantly in France due to government policies. This has led to a more qualified workforce and a corresponding rise in jobs for executives and intermediate professions, which require higher levels of education.
The feminization of employment refers to the increasing participation of women in the workforce. This was facilitated by legal changes (women no longer needed spousal permission to work) and extended schooling for girls, leading to higher qualification levels among women. Today, women occupy 48% of jobs in France.
To illustrate these evolutions in an exam, one can use data showing significant decreases in non-salaried employment (salarization), significant increases in employee or executive roles, or decreases in worker roles (tertiarization), increases in executive or intermediate professions (qualifications), and increases in women's employment rates (feminization).
