Immigration policy sounds easy to the uninitiated. It seems a matter of simply deciding how many people are needed to maintain the desired population, then let that many in and no more. Like drafting sheep. Politicians make it sound that simple when they announce they will cut immigration to a specified figure. If that was possible governments would keep to a set figure, but history shows they cannot.
Immigration flows have fluctuated wildly over the years, sometimes in response to slight changes of policy. The Labour Party will be hoping the target it announced yesterday is drastic enough to win votes at the election in September but not so drastic that it would bring the economy's growth to a shuddering halt.
Labour is forever warning that the growth of recent years has been largely driven by record immigration and it is right, though tourism and other trading sectors are contributing strongly. But if Labour is going to attribute the good times to excessive immigration and promise to cut it, the party will need to explain how it would maintain economic growth.
There is little doubt Labour's target would lower immigration, but probably by more than it would want. Even National's recent gentle step on the brake, denying residency permits for jobs earning less than the median wage, may be having a drastic impact on ethnic restaurants and some other service sectors. The evidence so far is anecdotal but by September the effects might be seen in economic and job statistics.
