<div>There's been a fair bit of work done on analysing the structural characteristics of language shift, although it's tricky to report on a language's structure alone as evidence of language shift. You might find the following useful:</div>

<div>I'd argue that, if you want to determine what sort of lexical loss can be considered language attrition, you'd best start with investigating what sort of value different elements of the language (and different semantic domains) have for the community that speaks it. </div>

After all, although many people think of minority languages as some sort of museum pieces that need to be preserved in some sort of arbitrarily identified state, they need to keep living naturally if they are to survive -- and naturally living languages do change over time.<br>
<br>But, on a related note, I think it would be very difficult to get a good picture of a language's relative health from a single "snapshot"; I think one would want to evaluate communicative competences of its speakers over time (if possible). I've recently begun a few few projects on endangered indigenous languages here in Colombia with the Ministry of Culture, and one of their initiatives has been to get indigenous communities to perform self-assessment surveys on the states of their language, precisely to figure out how many members speak a language well, how many speak it with difficulty, how many can understand it but not speak it, etc. The first round of such surveys (now complete) does give one some idea of what is going on with a language (for example, it may be reasonable to assume that if there are many more people who can't speak a language, or who can understand but not speak, than who can speak well, then that language is in trouble), but only subsequent rounds of surveys will give us the opportunity to track changes in these populations.<br>

How well are the speakers able to describe something monolingually? Assuming they're still in their native environment, are they capable of discussing day to day situations (in which they normally would use their language) without code switching?<br>
