Translation of Bevölkerungsdichte

I will built a function that will do all lowercase but meanwhile, I would be happy if it could be rewritten to lower case... Is it possible for you? They should all be lowercase, I did it inadvertently.
You wrote the first one 2 weeks ago. I was just thinking that 'LUCARAS' is a brandname, while the dictionary is a type. In plural, formal address would be 'vosotros' in Spain, and 'ustedes' in most of the Spanish speaking world.
What do you think of the current situation? Like you, I am writing letters, emails and other messages. Tomorrow I will leave, then I will go to my friend in Spain, where we are planing a beach vacation.
