The measurement of international travel has had to adapt to the Covid-19 pandemic
Covid-19 and related health protection measures have severely disrupted international travel. In this context, governments, tourism professionals and the general public expect official statistics to particularly enlighten them on the immediate consequences of the crisis for the sector – international tourism receipts (travel exports) accounted for 22% of France's services exports in 2019 – as well as on the first indications of recovery. However, the lockdown has stretched the usual statistical production methods to their limits, in particular due to the cessation of surveys of international travellers.
Banque de France travel statistics
The Banque de France is responsible for measuring France’s travel receipts and expenditure as part of its duty to compile balance of payments for France. Travel "receipts" (or exports) cover goods and services purchased by foreigners visiting France, including those acquired during day trips (border crossers, transit passengers, etc.). Conversely, travel "expenditure" (or imports) covers purchases made by French residents during their trips abroad.
Travel receipt statistical production relies primarily on the EVE (Enquête auprès des Visiteurs Étrangers) foreign visitors survey, which is carried out at the country’s points of exit (airports, harbours, train and bus stations, motorway rest areas, etc.) and questions a sample of non-resident visitors on the nature of their stay in France (spending, duration, types of accommodation, etc.). The findings are combined with information on exit flows from France (air, sea, rail or road passenger flows) to establish travel statistics for France that comply with the IMF’s international methodology and with European standards (Eurostat and ECB).
Statistical production during Covid-19
While lockdown put an end to direct questioning of foreign visitors, the public health measures introduced when it was lifted mean that normal survey conditions have not been restored. The Banque de France has therefore mobilised innovative data sources, such as payment cards and mobile networks, to ensure statistical production continues.
Payment card data gathered from banking institutions are traditionally used as auxiliary sources or for advanced estimates. Their collection provides monthly totals for French card transactions abroad, and for foreign card transactions in France that are then fully broken down on the basis of the card's country of origin. Although these amounts do not correspond exactly to tourism receipts (due to French residents using foreign cards, tourists spending cash withdrawn in their country of origin, etc.) and do not provide a breakdown of receipts by type (accommodation, restaurants, etc.), they do allow us to estimate developments on a country-by-country basis. The differences between the card-based estimates and the consolidated findings of the EVE survey are therefore limited, averaging 2% over recent years. Card data have thus been widely used since the beginning of the crisis to estimate non-resident visitor spending in France by country of origin.
Mobile network data, processed as part of a partnership with a national operator, allow us to determine the number of nights spent by foreign visitors in France. The country of origin is established through the nationality of the identified SIM cards, with similar difficulties arising to those encountered using payment card data (residents with SIM cards from another country, for example). These data quickly become available after the end of each month and are thus a valuable tool for monitoring international tourist traffic.
Lastly, regular contacts between central banks and national statistical institutes in the European Union, which have been greatly enhanced since lockdown began, have facilitated the sharing of best practices and data in order to corroborate international visitor "mirror data". For example, receipts from German residents visiting France measured by the Banque de France should match German residents’ expenditure in France measured by the Bundesbank.
