Methodology: How the Foot Load Index Was Calculated

By , Certified Orthotist with an MSc in Rehabilitation Science (SAARC) and expertise in research and development

What the index measures

The Foot Load Index estimates how much daily physical load a job is likely to place on the feet. It scores jobs based on seven work-related factors: standing demand, walking or movement, load-bearing or manual strain, hard-surface exposure, outdoor heat exposure, shift-duration risk, and footwear restriction. Each job receives a score out of 100.

What the index does not measure

  • Exact hours spent standing
  • Number of steps taken per shift
  • Rates of foot pain by occupation
  • Injury risk by occupation
  • Medical conditions
  • Long-term health outcomes
  • Individual worker experience

Scope of the analysis

This analysis covers non-agricultural Indian occupations. Agricultural jobs were excluded. The analysis includes both formal and informal non-agricultural work, including construction helpers, street vendors, porters, delivery workers, domestic workers, and other physically active jobs. The article uses reader-friendly job titles, while the methodology relies on official occupation categories and job descriptions.

Source base

  1. Recent labour-force context: PLFS material from MoSPI was used to provide current labour-market context. PLFS is useful for understanding employment and labour-force indicators, but it does not provide standing-time data by job.
  2. Official occupation classification: India’s National Classification of Occupations 2015 was used to identify and group occupations. NCO-2015 is a classification framework, not a measurement of foot load.
  3. Official occupation descriptions: NCO Volume II-A and Volume II-B were used to understand what different occupations involve.
  4. National Career Service role documents: NCS role documents were used where they gave clearer job-level descriptions, such as for courier delivery and housekeeping.

Score formula

Factor points = (factor score / 5) x factor weight. The total Foot Load Score is the sum of all weighted factor points. For example, if a job scores 5 out of 5 on standing demand, it receives the full 30 points for that factor. If a job scores 3 out of 5 on standing demand, it receives 18 points.

Job-by-job scoring notes

Construction labourers and helpers

Construction labourers and helpers scored highest because the role combines standing, movement across worksites, manual strain, hard or uneven surfaces, outdoor exposure, and possible work-footwear requirements.

Traffic police and field police roles

This score applies to field-duty and traffic-related policing, not desk-based police roles. These roles scored high because they can combine standing, walking, outdoor heat, public-road exposure, shift duty, and uniform footwear.

Porters and transport support workers

Porters and transport support workers scored high because carrying and walking are central to the role. This category includes workers who move luggage, parcels, or goods through transport, hospitality, station, airport, and similar spaces.

Warehouse workers and loaders

Warehouse workers and loaders scored high because the role involves moving through storage areas, loading, unloading, stacking, lifting, and handling goods on hard floors.

Delivery and package workers

Delivery and package workers scored high because the job is field-based and involves collecting packages, delivering them to customers, local travel, possible overtime, and repeated movement.

Security guards

Security guards scored high because guarding work can involve long standing duty, patrolling or checking, shift work, outdoor or semi-outdoor exposure, and uniform footwear.

Nurses and hospital support staff

Nurses and hospital support staff scored high because patient-care work can involve standing, movement between patients or wards, hard hospital floors, and shift intensity. The score does not claim exact standing hours.

Street vendors and hawkers

Street vendors and hawkers scored high because many operate while standing in public spaces, often outdoors and on hard surfaces. Load-bearing varies by vendor type, so the load score was kept moderate.

Restaurant and hotel service staff

Restaurant and hotel service staff scored high because service work can involve standing, walking, hard floors, long service shifts, and footwear or uniform expectations.

Domestic workers and housekeeping staff

Domestic workers and housekeeping staff scored moderate-high because cleaning work involves physical activity, sweeping, mopping, wiping, moving around properties, and possible long work hours or overtime.

Factory and manufacturing labourers

Factory and manufacturing labourers scored moderate-high because many such jobs involve standing, repetitive work, material handling, hard factory floors, shift work, and possible safety footwear. This is a broad category, so the article should not imply every factory job has the same physical profile.

Retail sales staff

Retail sales staff scored moderate-high because shop-floor and counter work can involve prolonged standing on hard indoor floors, customer-facing service, and long store hours.

Salon workers

Salon workers scored moderate-high because hair and beauty service work is standing-heavy, but typically involves less load-bearing, outdoor heat, and movement than higher-ranked jobs.

Teachers

Teachers scored moderate because teaching can involve standing and classroom movement, but usually involves less load-bearing work, outdoor exposure, and physical strain than the other jobs in the shortlist.

Limitations

  • It is a modelled index and does not measure exact hours spent standing.
  • Some job categories are broad. Factory work, police work, hospitality work, and nursing can vary significantly by workplace and role.
  • The ranking estimates likely foot load from job characteristics. It does not measure health outcomes.
  • Informal work can vary widely by region, employer, workplace, and season.
  • The score weights are editorial and methodological choices. They are published for transparency, but they are not an official government scale.
