Position Generator Method
Also known as: position generator, Lin position generator, accessed social capital instrument, occupational position generator
The position generator, developed by Nan Lin and colleagues, is a survey instrument for measuring an individual's social capital — the resources embedded in their personal network. Respondents are presented with a sample of occupations spanning the prestige hierarchy and asked, for each, whether they know anyone in that job. From these answers, the method derives indicators such as the number of positions accessed (extensity), the highest-prestige position reachable (upper reachability), and the range of prestige spanned, summarizing the volume and diversity of resources a person can mobilize through their contacts.
Key highlights
- Economical and standardized: a short, fixed list yields comparable measures across respondents and countries.
- Anchors social capital in the validated occupational prestige hierarchy.
- Produces interpretable indicators of volume (extensity), height (upper reachability), and diversity (range).
- Less subject to recall and naming bias than free-recall name generators.

When to use it
Use the position generator when you want to measure accessed social capital — the resources potentially available through a person's network — in a survey, in a standardized, economical, and cross-nationally comparable way. It excels in large representative samples where name generators would be too burdensome, and it ties social capital to the well-established occupational prestige hierarchy. It measures access (potential), not mobilization (actual use), and depends on a well-chosen occupation list calibrated to the society; it does not capture the structure of the network or non-occupational resources. For concrete resource access by domain, the resource generator is an alternative; for the composition of close ties, use a name generator.
Strengths & limitations
- Economical and standardized: a short, fixed list yields comparable measures across respondents and countries.
- Anchors social capital in the validated occupational prestige hierarchy.
- Produces interpretable indicators of volume (extensity), height (upper reachability), and diversity (range).
- Less subject to recall and naming bias than free-recall name generators.
- Measures potential access to resources, not whether they are actually mobilized.
- Captures only occupation-linked resources, missing non-occupational forms of support.
- Quality depends on choosing an occupation sample well-calibrated to the society's prestige structure.
- Reveals nothing about the structure (density, brokerage) of the respondent's network.

Frequently asked
What is the difference between the position generator and a name generator?
A name generator asks respondents to list specific people they are connected to (e.g., discussion partners), capturing the composition and structure of close ties but biased toward strong, similar contacts. The position generator instead probes a fixed list of occupations for any contact in each, measuring the range and height of accessed resources without naming individuals. The former maps the network; the latter measures resource access.
Does the position generator measure social capital one has or social capital one uses?
It measures accessed (potential) social capital: the resources reachable through one's network. It does not measure mobilized social capital — whether those resources are actually called upon. Access is a precondition for mobilization, but the two are distinct and the position generator speaks only to the former.
How is the occupation list constructed?
Researchers select a sample of occupations, typically 10–30, chosen to span the society's full prestige or socioeconomic range as evenly as possible, often using occupational prestige scores or socioeconomic indices. The list must be calibrated to the specific country and time, since occupational structures and prestige differ across societies.
