The process by which event attendees may become involved, or more involved, in an activity related to the event they have attended
Advanced Impacts
Impacts, the assessment of which is likely to require a significant piece of work using a specialist contractor/research company, and possibly over a long duration. Likely high cost.
A general statement that sets out the overall goal of staging an event. An aim does not go into detail or describe specific tasks but it should explain 'why' the event is being staged.
Audience profile
A description of the type of people who attend an event, expressed in terms such as gender, age, ethnicity, disability, place of residence, socio-economic group, educational attainment, or employment status
Audience representativeness
The extent to which the audience profile reflects the profile of a given population (eg. local, regional or national)
Basic Impacts
Impacts, the assessment of which can probably be undertaken reasonably easily using existing 'in-house' or event organiser data. Cost likely to be minimal.
Behaviour change
The adoption of new ways of doing things as a direct result of attendance at an event or its ancillary programmes.
Carbon footprint
The total set of greenhouse gas emissions caused directly and indirectly by an individual, organisation, event or product (UK Carbon Trust 2008).
Casual visitor
A visitor for whom the event is not the primary motivation for being in the host economy.
Commercial Stayers
Event-specific visitors staying overnight in the host economy and making use of hotels or other paid accommodation. Anyone staying commercially outside the host economy should be regarded as a day visitor.
Convenience sampling
The practice, where random sampling is not practical, of surveying as large a sample of an event population as possible in order that i) it should represent the wider population as reasonably as possible and (ii) the size of the sample minimises any potential biases
Day Visitors
Event-specific visitors not staying either commercially or non-commercially in the host economy. This group includes people staying at home / commercially / non-commercially outside the host economy.
Economic activity that would have occurred regardless of an event being held in the host economy, for example, expenditure by residents of the host economy with local suppliers linked to the event.
Direct Economic Impact
The amount of additional expenditure generated in the host economy by way of the spending by event-specific visitors and organisers that is directly attributable to the staging of the event.
The volume of normal activity displaced by an event, for example, normal tourists to an area may be crowded-out by event related visitors. This is more relevant for mega events and / or in the case of popular tourist destinations.
Event population
The total number of people attending or engaged in an event, including spectators, athletes or performers, support staff, media, sponsors, officials and volunteers
Gross Value Added (GVA) measures the economic added value created when producing a good or providing a service. GVA is the grand total of all revenues, from final sales and (net) subsidies, which are incomes into businesses. Those incomes are then used to cover expenses (wages & salaries, dividends), savings (profits, depreciation), and (indirect) taxes. To simplify, it is the difference between the price paid for a good or service and the cost of inputs used up in its production, and is mainly measured by profits plus wages. 
Host Economy
The geographical area under consideration for economic impact assessment. The criteria used to define the host economy will usually vary based on the scale of the event and the agency responsible for commissioning the research.
Intermediate Impacts
Impacts, the assessment of which is likely to require some research, but which could be organised by an event organiser or generalist research company. Moderate cost depending on scope.
Event-related activity that results in money being expatriated from the defined host economy, for example, expenditure by local residents made with non-local vendors working at an event.
Local Resident
Someone who is normally resident within the confines of the defined host economy.
Longitudinal research
Research that tracks the attitudes, viewpoints, behaviours etc. of selected individuals over a period of time
Mass participation events
Large-scale events designed to attract a significant number of participants from the general public. In sport, such events often permit recreational participants to take part alongside elite competitors.
Multipliers are used to assess the secondary impacts of the first round of visitor and organisational spending ('Direct Economic Impact') in the host economy. An output multiplier measures the impact of the initial visitor and organiser spend on the total business turnover in the host economy. An income multiplier measures the overall increase in household income of local residents.
No-stadium methodology
A method of estimating attendance at an event that takes place at a venue other than a stadium or other clearly enclosed space
Non-Commercial Stayers
Event-specific visitors staying overnight in the host economy but not paying for their accommodation, for example, people staying with friends or relatives. Anyone staying non-commercially outside the host economy should be regarded as a day visitor.
A specific statement relating to the overall aim of staging an event. Objectives should go into detail and should explain the steps to be implemented to deliver the aim.
Omnibus surveys
A survey covering a number of topics, usually for different clients. The samples tend to be nationally representative and composed of types of people for which there is a general demand. Clients are charged by the market research agency on the basis of the questionnaire space or the number of questions required. (Market , Social & Opinion Research – see
Open access methodology
A method of estimating attendance at events that provide spectators with free and generally unrestricted viewing access
Organiser Spend
Expenditure made by organisers with suppliers operating in the host economy net of event revenue generated from within the host economy.
Primary research
Primary research (also called field research) involves the collection of data that does not already exist. This can be through numerous forms, including questionnaires and telephone interviews.
Qualitative research
Research that involves the use of methods such as depth interviews or focus group discussions and which is designed to help establish how people feel (eg. about their attendance at an event) and why they feel as they do. Samples tend to be smaller than those used in quantitative research.
Quantitative research
Research that involves the use of sampling techniques (such as surveys of event attendees or participants), the results of which can be expressed numerically
Random sampling
The practice of surveying a population in which every element in the population has an equal chance of being selected, and in which the resulting sample is representative of the population from which it has been drawn
Someone who is normally resident outside the defined host economy.
