In 2007, was immigration sufficient to make up for the decreasing population sizes in spain and portugal?
why or why not?

Spain has had steadily growing immigration rates starting from the beginning of the 21st century, in particular between 1995 and 2007. By 2007, 12 percent of the total population accounted for immigrants.

Meanwhile, the population started to decrease only in 2010 due to the Great Recession. The debt crisis in the EU that has followed only further exacerbated this issue and both native Spaniards and earlier immigrants found Spain unattractive due to high unemployment rates.
