Weighted Ego Network Analysis
Weighted Ego Network Analysis (Tie-Strength-Aware Personal Network Analysis) · Also known as: weighted personal network analysis, ego-centered weighted network analysis, weighted egonet analysis, tie-strength ego network analysis
Weighted ego network analysis examines the personal network of a focal actor (the ego) and incorporates tie strength — measured as interaction frequency, closeness, or resource exchange — as edge weights. By moving beyond simple presence or absence of a tie, it captures how much each relationship matters and how those varying strengths shape outcomes such as social support, information access, or influence.

When to use it
Use weighted ego network analysis when you have or can collect data on the focal actors' personal networks together with a meaningful measure of tie strength, and when your research question concerns how the intensity of relationships — not just their existence — affects individual-level outcomes. It is well suited to survey-based studies of social support, health behavior, professional networking, and information diffusion. Avoid it when tie-strength data are unavailable or unreliable (forcing a binary approach is preferable to using arbitrary weights), when sample sizes of ego networks are very small (fewer than five alters on average), or when your interest is in system-level network properties rather than individual-level personal networks.
Strengths & limitations
- Captures heterogeneity in relationship intensity that binary ego network analysis misses.
- Compatible with standard survey methods; name generators and tie-strength scales are well-validated.
- Weighted versions of density, effective size, and constraint provide nuanced structural measures.
- Scales well to large samples of egos without requiring full network data collection.
- Integrates naturally with regression and multilevel models for outcome prediction.
- Tie-strength operationalization varies widely across studies, limiting comparability.
- Self-reported weights are subject to recall bias and social desirability effects.
- Does not capture the full network context beyond the ego's immediate neighborhood.
- Alter-alter tie weights are often missing, incomplete, or hard to collect reliably.
Frequently asked
What is the most common way to measure tie strength in surveys?
Self-reported frequency of contact (e.g., how often do you interact with this person on a 1–5 scale) and perceived closeness or emotional intensity are the most common operationalizations. Multiple indicators can be averaged into a composite weight.
Do I need alter-alter tie data to do weighted ego network analysis?
No. Ego-alter weights alone allow you to compute weighted degree, weighted centrality, and modified versions of Burt's constraint. Alter-alter ties are needed only if you want density or clustering measures within the ego network.
How is weighted ego network analysis different from whole-network analysis?
Ego network analysis focuses on the local neighborhood of individual focal actors and is collected through surveys, not observation of a complete network. Whole-network analysis maps all ties among a bounded population and requires full roster or observation data.
Can I compare weighted ego networks across individuals?
Yes, but normalize for network size. Weighted density divides total tie weight by maximum possible weight and is comparable across egos with different numbers of alters. Raw weighted degree confounds network size with tie intensity.
What software is available for weighted ego network analysis?
EgoNet (open-source) is purpose-built for ego network surveys and analysis. igraph (R/Python) and NetworkX (Python) compute weighted centrality metrics. Burt's constraint can be computed manually or via the ego package in R.
