Household Food Insecurity Access Scale
Also known as: HFIAS, Food Insecurity Access Scale
The HFIAS is a 9-item survey designed to measure the frequency and severity of food insecurity at the household level in resource-limited settings. Developed by the FANTA Project in 2007, it assesses four domains of food access: anxiety, dietary diversity, food consumption frequency, and household member deprivation. It is widely used in low- and middle-income countries for program evaluation and surveillance.

When to use it
The HFIAS is the standard measure for food insecurity surveillance in low- and middle-income countries and humanitarian settings. Use in household surveys, program evaluations, national nutrition surveys, and livelihood assessments. Particularly valuable where literacy constraints make longer instruments impractical. Suitable for populations in rural and urban settings experiencing variable access to food. Recommended for monitoring the impact of food assistance, cash transfer, and agricultural development programs.
Strengths & limitations
- Validated and widely used internationally; available in >30 languages with demonstrated psychometric equivalence.
- Captures four conceptually distinct domains of food insecurity (anxiety, dietary change, meal frequency, hunger).
- Ordinal scoring provides simple categorical classification suitable for policy and program targeting.
- Brief administration time (10–15 minutes) enables integration into larger household surveys without excessive respondent burden.
- Sensitive to program impacts; responsive to changes in livelihood, income, and food availability.
- Ordinal scale (not interval); cannot calculate means or use parametric statistics without converting to food insecurity prevalence categories.
- Relies on household head recall over 30-day period; subject to recall bias, particularly in settings with seasonal food stress.
- Does not measure individual-level food insecurity within the household; assumes equitable distribution of food.
- Does not capture nutritional adequacy or micronutrient deficiency; measures access, not intake quality or quantity.
- May not be sensitive to transitory or very acute food emergencies; 30-day recall period masks day-to-day fluctuations.
Frequently asked
Can HFIAS be administered by phone or self-reported, or must it be interviewer-administered?
HFIAS is validated as interviewer-administered in face-to-face settings. Some data collection platforms now enable audio-recorded phone administration with trained interviewers, though this introduces risk of bias. Self-administered written versions are not recommended, as literacy constraints in target populations limit validity. Interviewer presence allows clarification of item phrasing and ensures data quality.
What is the minimum and maximum HFIAS score, and what do they indicate?
Minimum score is 0 (food secure; zero affirmative responses across nine items). Maximum score is 9 (severely food insecure; all nine items endorsed). Interpretation: 0 = food secure; 1–3 = mildly food insecure; 4–6 = moderately food insecure; 7–9 = severely food insecure. Scores follow the natural progression of food insecurity severity.
How often should HFIAS be administered, and is there a preferred season?
Frequency depends on program design and research question. Typical evaluation designs use baseline (before intervention) and endline (12–24 months post-intervention). For surveillance, annual administration during the same season is standard. If the target population experiences seasonal food stress, administer at the same time in each year to avoid confounding seasonal variation with program effects.
Can HFIAS scores be averaged or compared statistically across households or time periods?
No. HFIAS is ordinal; raw summed scores should not be averaged. Instead, report frequencies in each category (food secure, mildly, moderately, severely insecure). For analysis, use the categorical classification or convert to binary prevalence (food insecure = any affirmative response; food secure = zero responses). Some analyses collapse categories (e.g., food insecure = 1–9; food secure = 0) for prevalence reporting.
