Migration monitoring

Total by year, 1973

Totals shown here are the original numbers recorded each year. No adjustments are made according to effort or others aspects are made here. Hence, the numbers are not, as reported here, suitable for long term trends.

Long term average does not include the most recent year, making it possible to compare this year with previous years. For long time trends adjusted figures are used, (more here - environmental monitoring).
